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.
Grand Duchy of LithuaniaThe Grand Duchy of Lithuania was a European state that existed from the 13th century to the late 18th century, when the territory was partitioned in 1795 among the Russian Empire, the Kingdom of Prussia, and the Habsburg Empire of Austria. The state was founded by Lithuanians, who were at the time a polytheistic nation born from several united Baltic tribes from Aukštaitija. The Grand Duchy expanded to include large portions of the former Kievan Rus' and other neighbouring states, including what is now Belarus, Lithuania, most of Ukraine as well as parts of Latvia, Moldova, Poland and Russia.
Demographics of UkraineAccording to the United Nations, Ukraine has a population of 36,744,636 as of 2023. This is a steep decline from 2020, when it had a population of almost 44 million people. This is in large part due to the ongoing Ukrainian refugee crisis, and loss of territory caused by Russia's invasion of Ukraine. In addition, it should be noted that the most recent (and only) census of a post-Soviet Ukraine occurred over 20 years ago, in 2001. Thus, much of the information presented here could be inaccurate and/or outdated.
