It was first mentioned in 1626, but it mostly stagnated until 1785, when after the death of Akim Vasilyevich Maltsov, his widow, Marya, bought out a factory from Yevdokiya, the widow of Alexander Vasilyevich Maltsov, and decided to expand its production. In 1790, in a forest near Dyatkovo, Marya Maltsova built the now famous glass and crystal factory, the quality of products of which was comparable to that of the plant in Gus. The workers' settlement around the plant soon grew in size and absorbed the village of Dyatkovo. In 1798, the ownership of the company passed to Ivan Akimovich Maltsov, who created an entire industrial empire centered in Dyatkovo. In 1853, his business was continued by his son Sergey. By then, 100,000 people were employed by Maltsov's factories, which had their own currency, police force, and a long railway. In 1918, when all of the Maltsov's factories were nationalized, the "State Maltsov Factory District" trust centered in Dyatkovo was established. In 1929, Dyatkovsky District produced about 10% of all the window glass produced in the Soviet Union. Town status was granted to Dyatkovo in 1938. Bryansk Oblast was a center of partisan movement during World War II. The German Army occupied Dyatkovo on October 9, 1941. In February 1942, Soviet partisans managed to retake power in Dyatkovo and neighboring villages. The area was deeply inside Nazi-occupied territory. The partisans ran a hospital and various shops but were overrun by the Nazis in June 1942. The Red Army retook Dyatkovo on September 15, 1943.
Dyatkovo is most noted for its lead crystal factory, furniture factory, and the Lead Crystal Museum, the largest museum of artistic glass in the country.
Religion
The Dyatkovo Transfiguration Church was opened in 1810. Its paintings were done in the Italian style and the iconostasis was made of crystal, as was the church's enormous chandelier. After the demolition of the church in 1929, the crystal iconostasis was lost. In 2003, new Dyatkovo church was built in honor of the iconNeopalimaya Kupina. The church possesses the world's only crystal iconostasis, which was made by the Dyatkovo Crystal Factory and which weighs about three tons.
