Batavia was a previous name for which modern European country?

The Batavian Republic was the successor of the Republic of the Seven United Netherlands. It was proclaimed on 19 January 1795, and ended on 5 June 1806, with the accession of Louis I to the throne of Holland. From October 1801 onward, it was known as the Batavian Commonwealth (Dutch: Bataafs Gemenebest). Both names refer to the Germanic tribe of the Batavians, representing both the Dutch ancestry and their ancient quest for liberty in their nationalistic lore.

In early 1795, intervention by French revolutionary forces led to the downfall of the old Dutch Republic. The new Republic enjoyed widespread support from the Dutch population and was the product of a genuine popular revolution. Nevertheless, it clearly was founded with the armed support of the revolutionary French Republic. The Batavian Republic became a client state, the first of the "sister-republics" and later part of the French Empire of Napoleon Bonaparte, and its politics were deeply influenced by the French who supported no fewer than three coups d'état to bring the different political factions to power that France favored at different moments in its own political development. Nevertheless, the process of creating a written Dutch constitution was mainly driven by internal political factors, not by French influence, until Napoleon forced the Dutch government to accept his brother as monarch.
