Molotschna Colony or Molochna Colony was a Russian Mennonite settlement in what is now Zaporizhia Oblast in Ukraine. Today the central village is called Molochansk and it has a population of under 10,000. The settlement is named after the Molochna River which forms its western boundary. Today the land falls mostly within the Tokmatskyi and Chernihivskyi Raions. The nearest large city is Melitopol to the southwest of Molochansk.
The colony of Molotschna was founded in 1804 by Mennonite settlers from West Prussia and consisted of 57 villages. The city initially was called Halbstadt (Half-city). Known as the New Colony, it was the second and largest settlement of Mennonites in the Russian Empire. In the late 19th century, hundreds of people left this colony to settle in North America. Colonies there had groups that later relocated to Latin America, where Mennonites settled in several countries. After many ethnic Germans left or were deported during and after the last days of World War II, this area became populated largely by Ukrainians.
After the first Mennonite colony within the Russian Empire, Chortitza, was founded in 1789, Mennonite visitors found the freedoms and free land of Southern Ukraine an attractive alternative in view of restrictions placed on them in West Prussia. The imperial Russian government wanted more settlers with the valuable agricultural and craft skills of the Mennonites. In 1800 Paul I of Russia enacted a Privilegium (official privileges) for Mennonites, granting them exemption from military service "for all time". In West Prussia King Frederick William III was making it difficult for Mennonites to acquire land, because of their refusal to serve in the military due to their pacifist religious beliefs. Another reason to immigrate was fear of the changes brought about by the French Revolution. Refuge in Russia was seen as a more secure alternative.
