First Barrier Treaty

The First Barrier Treaty, signed on October 29, 1709, was an agreement between Great Britain and the United Provinces of the Netherlands. This treaty aimed to provide the Dutch Republic with a defensive buffer against France by allowing them to garrison towns along the southern border of the Spanish Netherlands. In return, the United Provinces agreed to support the succession of the House of Hanover in Great Britain. However, Great Britain later set this treaty aside, leading to a Second Barrier Treaty in 1713 with terms less favorable to the Dutch. The details were further modified by a Third Barrier Treaty in 1715.1
