Nevertheless, Lithuania's state sovereignty was preserved: the treasury, the currency, the laws and the army remained independent.
Lithuania began to recover only towards the end of the 19th century, the period known as the "spring of nations." A struggle for national culture and reinstitution of writing spread over the greater part of the country.
Lithuania was admitted to the League of Nations in 1921.
Lithuania Minor (or Prussian Lithuania, Lithuanian Mažoji Lietuva and Prūsų Lietuva respectively) is one of five ethnographic regions of Lithuania.
Lithuania Minor territory was comprised of the current Kaliningrad Oblast (excluding the city of Kaliningrad and its surroundings), a few territories in northern Poland as well as the following territories in modern-day Lithuania: the Klaipėda district municipality, the Šilutė district municipality, Klaipėda city, Pagėgiai municipality, and Neringa municipality.
This region always was an important center for Lithuanian culture, which was persecuted in other part of Lithuania, especially in the first half of the 19th century, when it was occupied by Russia and previously polonized.
