History
Krasnomaysky was known since the 15th century as the village of Klyuchino (Klyuchinskaya Pustosh). Klyuchino was located on the bank of the Shlina, close to the portage to the Tvertsa River, one of the most popular trade routed of the medieval Russia. In 1858–59, merchant Samarin built a chemical plant, and the settlement was founded to serve the plant. Subsequently, the plant was sold to merchant Andrey Bolotin, who converted it into a glass-making factory. The factory started operation in 1873, and became the first one in Russia to produce colored glass of a broad range of colors. At the time, the settlement was located in Vyshnevolotsky Uyezd of Tver Governorate. The factory was nationalized in 1920 and renamed Krasny May ("Red May", referring to International Workers' Day) in 1923.

On August 12, 1929 the governorates and uyezds were abolished. Vyshnevolotsky District, with the administrative center in Vyshny Volochyok, was established within Tver Okrug of Moscow Oblast, and Krasnomaysky became a part of the district. On July 23, 1930, the okrugs were abolished, and the districts were directly subordinated to the oblast. On January 29, 1935 Kalinin Oblast was established, and Vyshnevolotsky District was transferred to Kalinin Oblast. In 1990, Kalinin Oblast was renamed Tver Oblast.
