Former countries in Europe after 1815

The scope of this article begins in 1815, after a round of negotiations about European borders and spheres of influence were agreed upon at the Congress of Vienna.[3] The Congress of Vienna was a nine-month, pan-European meeting of statesmen who met to settle the many issues arising from the destabilising impact of the French Revolutionary Wars, the Napoleonic Wars, and the dissolution of the Holy Roman Empire.[4]

The immediate background was Napoleonic France's defeat and surrender in May 1814, which brought an end to twenty-five years of nearly continuous war during which France had caused the annexation or geopolitical reorganisation of myriad European microstates as well as some larger ones. The Congress of Vienna was the first of a series of international meetings that came to be known as the Concert of Europe, which was an attempt to forge a peaceful balance of power in Europe,[5] including restoring or reorganising many of the states which had previously been removed from Europe's political map.

This is a list of all the independent countries or puppet states that existed between 1815 and the present day that no longer exist. (Lifespan of each is based on that country's sovereignty. This means that those countries may have existed outside of those dates as well but not under full independence.)
