Much uncertainty surrounds their migration to China. It is believed that, upon their arrival to the imperial capital, the Albazinians met the descendants of 33 Cossacks that had been captured by the Chinese in 1667 and several Cossacks that had settled in Beijing as early as 1649 and had become the parishioners of the
South Roman Catholic Cathedral in the city. The veracity of this oral tradition about the pre-Albazinian Russian diaspora in China is open to question. The Albazinians formed a separate contingent of the imperial guard, known as the "unit of the yellow-stripe standard". Their first leader was Ananiy Uruslanov or Ulangeri, a Tatar in the employ of the Manchu. The Russian surnames Yakovlev, Dubinin and Romanov were rendered in Chinese as Yao (姚), Du (杜) and Luo (
Simplified Chinese: 罗,
Traditional Chinese: 羅). The Qing gave permission for
Solon widows to marry the Albazinians. They married with Mongol and Manchu women. The women available for marriage to the Albazinians were criminals from Beijing's jails. Their priest, Maxim Leontiev, was allowed to hold
divine service in a deserted
Lamaist shrine. An old icon of
St. Nicholas, evacuated by the Cossacks from Albazin, was placed in this unusual church, dedicated to the Holy Wisdom. The Albazinian company was placed into the Manchu Bordered Yellow Banner and lived in the northeast of the "Tartar city" in Beijing. The Albazians were made into a
Baoyi company, not a military company. Although the descendants of the Cossacks intermarried with the Chinese and gradually lost their command of the Russian language, the
Russian Orthodox Church regularly sent missions to Beijing, starting in 1713. As a result, the Albazinians came to form the core of the
Chinese Orthodox Church. In 1831,
Ioakinf Bichurin reported that there were 94 Albazinians in the capital of China. Other Russian travellers noted that, apart from their faith, the Albazinians were thoroughly Sinicized and bore little physical resemblance to the Russians. By the end of the 19th century, their number was estimated at 1,000. The
Boxer Rebellion entailed the persecution of all Christians and Europeans in China. The Russian Orthodox Church claims that 222 Orthodox Chinese were martyred on 11 June 1900, including Father Mitrofan, who was later declared a holy
martyr. An Orthodox chapel used to mark the burial place of the
Chinese Orthodox martyrs in Beijing. It was destroyed in 1956 at the urging of the Soviet ambassador in China. Although several Albazinian families found it reasonable to move to the
Soviet Union during the
Cultural Revolution, the bulk of them still reside in Beijing and
Tianjin. ==Later history==
