Novoselenginsk

Novoselenginsk (Russian: Новоселенги́нск) is a rural locality (a settlement) in Selenginsky District of the Republic of Buryatia, Russia,[1] located on the Selenge River south of Lake Baikal.

In 1688, the ostrog was besieged by the Khalkha Mongols for two months, but they had to withdraw when their main territory was attacked by the Oirats.

The defence was led by Demian Mnohohrishny, an exiled Cossack who had previously played an important part in Ukrainian history.

In 1727-1730, Abram Petrovich Gannibal, Alexander Pushkin's African great-grandfather, was exiled here after Peter the Great's death.

The mission, which relocated to Khodon in 1828, was eventually suppressed in 1840 by the Holy Synod of the Russian Orthodox Church under Alexander I's successor, Nicholas I.

Also, while the location between the river and the mountain spurs greatly improved the defensive capabilities of the fort, it also impeded the development of transportation links.
