The Kolaba District Gazettee gives Pen's history as follows

In historical times Pen was under rule of the Silaharas of Shri Sthanak (Thana) from 9th to the 12th Century and subsequently it passed under the control of the Yadavas. When Shayastakhan was sent against Sivaji, a detachment of the Moghal army had been kept at Pen but it was subsequently routed by him. Parvatibai, the wife of Sadasivrav Bhau, the hero of Panipat. In 1819 the easy communication with Bombay and with the Deccan by the Bor pass made Pen an important centre. Its chief prosperity lay in its salt beds. There was a considerable export of rice to Bombay. A number of carved stones about the town appear to belong to an unusually large temple of about the thirteenth or fourteenth century.

During the period of Shilahar kings, many temples of goddesses were built, including Jagdumba of Vashi. In the period of Chalukyas, grand temples of Shiva, like Rameshwar (रामेश्वर), Pataneshwar (पाटणेश्वर), Goteshwar (गोटेश्वर) and Vyaghreshwar (व्याघ्रेश्वर) were constructed

Vyagreshwar Temple Was built by Shri Senapati Prataprao Gujar. Ordered by Shri Chhatrapati Shivaji Maharaj in Pen Swary and later worshipped by Langi's of Pen as it is their clan deity.

In Chhatrapati Shivaji Maharaj era, Shayistekhan's raid on Deccan led to major fights in Pen between Moghals and Marathas. Initially the Moghal army led by Sardar Taherkhan occupied Pen's fort of Mahalmeera and looted surrounding villages, which included desecration of the grand temple of Goteshwar. Shivaji's army fought back. They defeated Kartalabkhan in nearby Umbarkhind and officer Balakhi, near Ratangad. Mahalmeera was also taken back on 27 February 1662 and the following day, after a valiant struggle, Pen's Bastion (presently, the site of Tehsil office) was secured by Shivaji's army. In this conquest, Sardar Vaghoji Tupe fought against an equally skillful Moghal officer but at the crucial moment, Tupe dealt a decisive blow which killed the officer and ensured Maratha victory. Vaghoji was also critically injured and died soon afterwards. Shivaji Maharaj visited Pen on two occasions, on 6 August 1668 and 11 May 1674.

Traditionally, Pen city was populated by Aagri, Brahmins and merchant's community as it was center of culture, education and trade. But now, the city of Pen has become an amalgam of several castes and religions. In the olden days, Pen was recognised primarily as a Chitpavan Brahmin dominated village, but today all Pen tehsil is dominated by Aagri Community. Agri community dwells in flatlands of Pen West, Hinterlands of Pen South-East are sparsely populated by tribal Katkari and Thakurs. Pen has a small Jewish community, the Bene Israel.

People in the Pen city are employed in various sectors such as trade/business, education, banking, industries, services, papad making (women's co-operatives) and most importantly, idol making!

Most villagers are dependent for livelihood on Paddy farming in monsoon. Various vegetables are also grown as by-products, especially in eastern part of the county.

The industrial belt in the western part of the county is causing a major problem of pollution in surrounding rural areas, creating health problems and reducing crop yields. Reliance Industries was promoting a Maha Mumbai Special Economic Zone, located around the town. A study conducted by Citizen's Research Collective on SEZ has called the Maha Mumbai Special Economic Zone a Special Exploitation Zone Land owners resisted the purchase of their land for the purpose and following a historic referendum on the issue, SEZ was cancelled. Land prices are soaring and economy is growing rapidly but there are some serious concerns about uneven and unjust development.
