"Ingermanland is the descendant of ancient Ingria in the area of the Gulf of Finland, the river basin of Neva and Lake Ladoga that became a Swedish province (in Swedish: Ingermanland) after the battles during the years 1570--1595 and 1610--1617. It included Jaanilinna (Ивангород), Jaama (Ямбург), Kaprio (Копорье) and Pähkinälinna (Орешек) county -- all together roughly 15,000 square kilometres. The area of Ingermanland extended 200 kilometres from the River Narva in the west to the River Lava in the east and from north to south 130 kilometres. From 1710 on, Ingermanland was part of St. Petersburg, from 1914 of Petrograd and from 1927 of the province of Leningrad."
