Trans-Nzoia County is a county in the former Rift Valley Province, Kenya, located between the Nzoia River and Mount Elgon, 380 km northwest of Nairobi. At its centre is the town of Kitale which is the county capital and largest town. It is bordered by the Republic of Uganda to the west, Bungoma and Kakamega Counties to the south, West Pokot County to the east, and Elgeyo Marakwet and Uasin Gishu Counties to the southeast. Trans Nzoia covers an area of 2495.5 square kilometres. The county has a cool and temperate climate, with daytime temperatures ranging from 23.4°C to 29.2°C and nighttime temperatures from 11.0°C to 13.5°C. It receives moderate rainfall, making it suitable for agriculture

Earliest known written records about the region show that Trans Nzoia was inhabited by the Maasai who, by the time of the arrival of colonial settlers, had died or left the district, some had died of illness, others had been killed in intertribal wars with the Suk (Pokot), and the remainder had mostly gone off in the direction of Ravine, though some had gone up the Elgon. After independence, many of the farms vacated by white settlers were bought by individuals from other ethnic groups in Kenya. Kitale, its capital town, is now majorly Luhya with inhabitants from other tribes in Kenya occupying almost less than 1% of the population.

The county is largely agricultural with both large scale and small scale wheat, maize and dairy farming. The county is referred to as the bread basket of Kenya for its role in food production in the country. The majority of its inhabitants are however generally poor.

Trans Nzoia is one of Kenya's forty-seven counties, established under the 2010 constitution. It is locally governed by the County Government of Trans Nzoia. The County Government Act allows the County Government to further decentralize its functions and services below the village with the approval of the Trans-Nzoia County Assembly. Governors are elected every five years in the Kenya General Elections. George Natembeya is the current governor since 2022, succeeding Patrick Khaemba who was the first governor of Trans Nzoia and led the county from 2013 to 2022.

Trans Nzoia County features predominantly flat terrain with gentle undulations rising towards the Cherang'any Hills in the east and Mount Elgon in the northwest. Mount Elgon, shared with Bungoma County and Uganda, is Kenya's second-highest peak and a significant environmental and wildlife conservation site. The county's altitude varies from 1,660 meters in Sikhendu Ward to 4,299 meters at Mount Elgon's peak.

The county is home to 15 rivers, including Sabwani, Rongai, Noigamaget, Suam, Kaptega, and Losourwa, which contribute to the Nzoia River system draining into Lake Victoria and Lake Turkana. These rivers are crucial for domestic use, small-scale irrigation, and have potential for hydroelectric power generation. However, they face threats from human activities such as encroachment and agriculture, which impact their catchment areas.

Trans Nzoia's forests, primarily located in Mount Elgon and Cherang'any Hills, are essential for the county's climate and water catchment. Human activities have reduced forest cover from 17% in 2013 to 15.1%, posing challenges for the local environment.

The county enjoys a cool, temperate climate with mean maximum daytime temperatures ranging from 23.4°C to 29.2°C and mean minimum nighttime temperatures between 11.0°C and 13.5°C. The highest temperature, about 34.2°C, occurs in February, and the lowest, around 6.5°C, is recorded in January. Annual rainfall varies from 1,000mm to 1,700mm, distributed across three main seasons: long rains (March-May), intermediate rains (June-August), and short rains (October-December). The long and intermediate rainy seasons are more reliable for agriculture. However, recent climate changes have led to increased occurrences of droughts, dry spells, and floods.

Trans Nzoia comprises five sub-counties: Kiminini, Saboti, Endebess, Kwanza, and Cherangany, which are further divided into 25 wards. As of the 2019 Census, the population was 990,341, consisting of 489,107 males, 501,206 females, and 28 intersex individuals. The county had 223,808 households with an average size of 4.4 people per household.

Kitale serves as the county's administrative center and main commercial hub. Other significant market centers include Kiminini, Kachibora, Saboti, and Endebess. The county is highly diverse, with residents from nearly all of Kenya's 44 ethnic groups, including the predominant Luhya and Kalenjin communities, as well as Kikuyu, Kisii, Luo, Teso, and Turkana among others.

Trans Nzoia County derives its name from the Nzoia River, a prominent geographical feature in the region. Here's an exploration of the toponymy related to Trans Nzoia:

1. Nzoia River: The county is named after the Nzoia River, which flows through the region. The name "Nzoia" is believed to have its origins in local dialects, though the exact etymology might vary.
2. "Trans" Prefix: The prefix "Trans" indicates "across" or "beyond" in Latin, suggesting that the name signifies "beyond the Nzoia River" or "across the Nzoia River". This term was commonly used during the colonial era to denote areas located on the other side of a prominent geographical feature.
3. Colonial Influence: During British colonial rule, the area around the Nzoia River and its surroundings were designated as "Trans Nzoia" to demarcate administrative regions. This naming convention persisted into the post-independence period, and Trans Nzoia County was formally established as an administrative unit within Kenya.
4. Historical Context: The naming of Trans Nzoia County reflects its geographical and historical significance as a region defined by the Nzoia River and its cultural, economic, and political interactions over time.

Overall, Trans Nzoia County's toponymy highlights the fusion of geographical, historical, and cultural elements that define its identity within Kenya.

Initially, the region was dominated by natural features like Mount Elgon, the Cherangani Hills, and the Nzoia River, which marked its boundaries. Early maps, such as those depicting "Qitale," show its significance as a route for slave traders from Uganda to the coast. Kitale, now the central town of Trans Nzoia, was even used as a resting place for these traders.

An article titled "At the Sign of the World's Cross Roads: Tsetse Fly and the Trans-Nzoia" from The Field magazine in September 1919 provides a detailed account of the early settlement and the challenges faced by settlers in the Trans-Nzoia region of Kenya. It highlights the following key points:

1. Tsetse Fly Infestation: One of the significant challenges in Trans-Nzoia was the presence of the tsetse fly, which caused sleeping sickness in both humans and animals. This pest was a major obstacle to settlement and agriculture, as it affected livestock and made large areas uninhabitable.
2. Early Settlement: The article discusses the arrival of early European settlers who faced numerous hardships, including diseases, lack of infrastructure, and the remoteness of the region. Despite these challenges, the settlers were determined to develop the land.
3. Agricultural Potential: Despite the difficulties, the region was recognized for its fertile soil and potential for agriculture. The settlers worked hard to clear the land, establish farms, and introduce crops and livestock that could thrive in the environment.
4. Infrastructure Development: The article notes the gradual development of infrastructure, including roads and railways, which facilitated better access to markets and resources. This development was crucial for the economic growth of the region.
5. Community Efforts: There was a strong sense of community among the settlers, who supported each other in overcoming the various challenges. They established social and support networks to improve living conditions and promote development.
6. Government Involvement: The colonial government played a role in supporting the settlement efforts by providing resources, conducting surveys, and implementing policies to encourage more settlers to move to Trans-Nzoia.

This early period in Trans-Nzoia's history is characterized by the settlers' resilience and the collaborative efforts to transform a challenging environment into a productive agricultural region.

The first formal attempts to settle Trans Nzoia began in 1913, when the government auctioned farms. However, the outbreak of World War I slowed this process, leaving many farms vacant. After the war, the Soldier Settlement Scheme in 1920-21 brought new settlers, marking the start of structured development. Despite initial hardships, including the lack of nearby banks and railheads, settlers persevered. Kitale started to emerge as an administrative and business center, and the appointment of a District Commissioner at Hoey’s Bridge facilitated governance and infrastructure development.

The social fabric of Trans Nzoia began to take shape with the establishment of various institutions. The Kitale Club, founded in 1924, became a hub for social activities. Religious institutions like St. Luke's Church and a Roman Catholic Church were built, catering to the spiritual needs of the community. Medical facilities were initially scarce, with a private house serving as a hospital run by nursing sisters. Over time, the district saw the establishment of more comprehensive healthcare and educational facilities, reflecting its growing complexity and self-sufficiency.

Agriculture played a pivotal role in Trans Nzoia’s development. The fertile plains and favorable climate conditions made it ideal for cultivating maize, wheat, pyrethrum, coffee, and tea. The success of these crops attracted more settlers and investment. The extension of the railway to Kitale, a project championed by Governor Sir Edward Grigg, significantly boosted agricultural and economic activities by improving the transport of goods and people.

Trans Nzoia’s landscape is marked by significant geographical features that contribute to its biodiversity and agricultural productivity. Mount Elgon, with its vast base and rich natural resources, and the Cherangani Hills, known for their varied scenery and rare wildlife, form natural boundaries and habitats. These areas support diverse flora and fauna, including the rare Bongo and the Lammergeyer. The district’s altitude ranges from 6,000 to 8,000 feet, with an average annual rainfall of 48 inches, further enhancing its suitability for agriculture.

The history of Trans Nzoia is also marked by notable figures and events. Abu Bakr, an early observer, provides a vivid account of the region in the early 20th century, describing its uninhabited state and the challenges faced by early settlers. Significant visits by royalty, such as the Prince of Wales (October 1928) and Queen Elizabeth the Queen Mother (1959), highlight the district’s growing importance over time.

Trans Nzoia County boasts a diverse and vibrant economy, with agriculture playing a central role. The county is known for its significant contributions to Kenya's food security, primarily through large-scale maize production. To enhance this sector, the County Government of Trans Nzoia has established milling plants in Kitale Town, Endebess, and Matisi, promoting value addition to agricultural produce. Furthermore, there is a strong focus on agricultural training, with colleges disseminating modern farming technologies. The county also invests in irrigation systems in areas like Endebess, Kwanza, Saboti, Cherangani, and Kiminini to ensure a reliable water supply for crops. Mechanization is made more accessible through subsidized agricultural machinery, including tractors, ploughs, and planters, supporting farmers in maximizing their productivity.

Tourism is another growing sector in Trans Nzoia County, with initiatives aimed at improving infrastructure and diversifying the tourism experience. Efforts include the preservation and protection of key sites, the establishment of tourist information centers, and the modernization of traditional bomas at the Kitale Museum. The county is also developing new tourism products such as amusement parks and eco-tourism ventures. To attract more visitors, comprehensive tourism marketing and investment strategies are being implemented, along with the classification of tourist establishments to ensure high standards of service.

Trade and commerce are vital to the county's economy, with significant investments in market infrastructure. The County Government of Trans Nzoia is renovating existing markets and constructing new business kiosks and sanitation blocks to create a conducive environment for traders. Trade shows and exhibitions are regularly hosted to promote local products and foster business growth. Additionally, the county is enhancing cross-border trade by forming and operationalizing cross-border associations, facilitating smoother trade relations with neighboring regions.

Through these strategic initiatives, Trans Nzoia County is steadily strengthening its economic foundation, ensuring sustainable growth and development across agriculture, tourism, and trade sectors.

Majority of people living in Trans Nzoia County are Christians. Prominent churches in the county include Anglican (ACK), Roman Catholic, Friends (Quakers), Seven-Day Adventist (SDA), and Presbyterians. There are numerous evangelical churches among them the Deliverance, African Inland Church (AIC), Africa Gospel Church (AGC),the Redeemed Church, PEFA, Christian Church International (CCI), Full Gospel and Kenya Assemblies of God (KAG). Other faiths such as Islam and Hinduism are also professed especially in major towns.

Jainism is also practiced by Oshwals in Kitale which is a religion that prescribes a path of non-violence towards all living beings while emphasising spiritual independence and equality. The indigenous Sabaot tribe or the 'Elgon Maasai' live near Mount Elgon and are a Kalenjin sub tribe. They value their culture and guard it with pride. They are traditionally pastoralists. They used to believe that their god lived in elevated places where they could not reach such as on top of Mount Elgon or up in the sky. However, due to influence of Christianity, education and intermarriage, most of these traditions have been replaced by modern culture, a reason why the one time pastoralists are now big farmers in the region.

Financial constraints further exacerbate these issues, leading to limited access to medical cover and weak health governance.

Infrastructure: The county's infrastructure is underdeveloped, with inadequate road and transport networks posing significant challenges. Technical skills and resources are insufficient, hindering the development of critical infrastructure. Collaboration with the national government and private sector is necessary to improve energy and transport infrastructure. Moreover, there is a need for better maintenance of government buildings and enhanced capacity to respond to fire emergencies and other disasters.

Agriculture: Agriculture, being the backbone of Trans Nzoia’s economy, faces several issues. Poor farming practices and environmental degradation have led to reduced agricultural productivity. There is a need to promote sustainable agricultural practices and enhance value addition in processing local produce. The county's agricultural sector also suffers from inadequate market infrastructure and poor transport networks, which limit access to markets and hinder economic growth.

Governance: Weak governance structures and inadequate legislative frameworks are significant hurdles in the county's development. The lack of structured inter-sectoral collaboration frameworks hampers coordinated efforts in addressing the county's development needs. Additionally, financial constraints and limited human resources affect the implementation of key development projects and programs.
