In October 1511, Julius proclaimed a Holy League against France. The new alliance included not only Spain and the Holy Roman Empire (which abandoned any pretense of adhering to the League of Cambrai in hopes of seizing Navarre from Queen Catherine and Lombardy from Louis), but also Henry VIII of England who, having decided to use the occasion as an excuse to expand his holdings in northern France, concluded the Treaty of Westminster—a pledge of mutual aid against the French—with Ferdinand on 17 November.
