The history of Zacharo begins in the middle of the 19th century. At the time of the Greek War of Independence, the area of Zacharo was sparsely populated. However, in the decades that followed, populations from the villages of the surrounding mountains started to migrate to the area. The town allegedly took its name from an inn, that belonged to a woman named Zacharoula. In 1881 Zacharo was officially proclaimed a community. In late August 2007, forest fires caused over 40 deaths, as well as extensive property damage. Zacharo was one of the worst-hit areas in Greece.

The economy of Zacharo relies on tourism as well as on agriculture. The pleasant Mediterranean climate, long Zacharo beach, the Kaiafas Lake, the Thermal Springs of Kaiafas and the adjacent Lapithas mountain draw many tourists, especially in summer. The agricultural sector is also a major source of income for the local economy. It is based on the cultivation of olive trees, for the production of olive oil. The variety of olive tree which prevails in the area is the Koroneiki, which is one of the most distinguished in Greece. The olive oil produced is of extra-virgin quality and is mostly exported to the international market. The Zacharo tomato is famed for its sweetness. When ripe, it is loaded with sugars (mainly fructose and inulin) to the extent that the sugar crystals are visible to the naked eye. Cultivation of the Zacharo tomato is all but extinct, as the cultivar does not grow well in greenhouses, has a short season, and its extreme fleshiness makes the fruit heavy and liable to squeezing and decay when packed.
