History
Officially, the area had come under control of Russia in 1858 after the Treaty of Aigun with China. The treaty set the Amur River as border between the two countries. Settlers began drifting in, mostly from the Trans-Baikal area, over the following years. The village of Golovino reaching a population of 400 by the year 1891, with a school, a post office, and a chapel. Another wave of population growth came in 1890–1910 with the construction of the Trans-Siberian Railway and the Amur Cart Road; these migrants were mostly from Central Russia and Volga regions. New villages spread north from the Amur along the Bira River.

The first large migration of Jews began in the 1920s, who founded at least half a dozen villages in the district. They established an Experimental Farm (later the Research Institute of Agriculture) to develop farming practices more appropriate to the area, as the heavy summer rains interfered with harvests and the soils and climate were different from European Russia. Until the 1930s, there were few roads and transportation centered on a 60-horsepower steamer that worked up and down the Bira from the Amur to the town of Birobidzhan. Good roads did not begin to appear until the 1950s-1960s.

The current district administration was formed in 1942 as the area was growing in importance and was supplying food to the war effort. At the time, there were 5,883 people in the district, on 1683 farms and 12 collectives. Late in 1942, the village of Valdgame contributed 250,000 rubles to support the squadron "Jewish Farmer". Agriculture improved in the post-war years with the introduction of fertilizers, pesticides, and crop rotation.
