The Republic of the Seven United Netherlands, also known as the United Provinces (of the Netherlands), and referred to in historiography as the Dutch Republic, was a confederation and great power that existed from 1588 until the Batavian Revolution in 1795. It was a predecessor state of the present-day Netherlands and the first independent Dutch nation state. The republic was established after seven Dutch provinces in the Spanish Netherlands revolted against Spanish rule, forming a mutual alliance against Spain in 1579 (the Union of Utrecht) and declaring their independence in 1581 (the Act of Abjuration), after which they confederated in 1588 (the Instruction of 12 April 1588) after the States General could not agree on a new monarch. The seven provinces it comprised were Groningen (present-day Groningen), Frisia (present-day Friesland), Overijssel (present-day Overijssel), Guelders (present-day Gelderland), Utrecht (present-day Utrecht), Holland (present-day North Holland and South Holland), and Zeeland (present-day Zeeland).
