Polish People's RepublicThe Polish People's Republic (Polska Rzeczpospolita Ludowa, PRL), or simply Poland (Polska), was a country in Central Europe that existed from 1947 to 1989 as the predecessor of the modern-day Republic of Poland. With a population of approximately 37.9 million near the end of its existence, it was the second most-populous communist and Eastern Bloc country in Europe. A unitary state with a Marxist–Leninist government, it was also one of the main signatories of the Warsaw Pact alliance.
Province of PosenThe Province of Posen (Provinz Posen; Prowincja Poznańska) was a province of the Kingdom of Prussia from 1848 to 1920. Posen was established in 1848 following the Greater Poland Uprising as a successor to the Grand Duchy of Posen, which in turn was annexed by Prussia in 1815 from Napoleon's Duchy of Warsaw. It became part of the German Empire in 1871. After World War I, Posen was briefly part of the Free State of Prussia within Weimar Germany, but was dissolved in 1920 when most of its territory was ceded to the Second Polish Republic by the Treaty of Versailles, and the remaining German territory was later re-organized into Posen-West Prussia in 1922.
National flagA national flag is a flag that represents and symbolizes a given nation. It is flown by the government of that nation, but can also be flown by its citizens. A national flag is typically designed with specific meanings for its colours and symbols, which may also be used separately from the flag as a symbol of the nation. The design of a national flag is sometimes altered after the occurrence of important historical events. The burning or destruction of a national flag is a greatly symbolic act.
Polish–Lithuanian CommonwealthThe Polish–Lithuanian Commonwealth, formally known as the Kingdom of Poland and the Grand Duchy of Lithuania, or simply Poland–Lithuania, was a bi-confederal state, sometimes called a federation, of Poland and Lithuania ruled by a common monarch in real union, who was both King of Poland and Grand Duke of Lithuania. It was one of the largest and most populous countries of 16th- to 17th-century Europe. At its largest territorial extent, in the early 17th century, the Commonwealth covered almost and as of 1618 sustained a multi-ethnic population of almost 12 million.
