German Quarter
In the sixteenth century Vasili III invited small numbers of craftsmen, traders and professionals to settle in Russia from areas that would later become Germany so that Muscovy could exploit their skills. These settlers (many of whom intended to stay only temporarily) were generally confined to the German Quarter in Moscow (which also included Dutch, British and other western or northern European settlers whom the Russians came to indiscriminately refer to as "Germans"). They were only gradually allowed in other cities, so as to prevent the spread of alien ideas to the general population.
