Political map of Europe & the Mediterranean 26 September 1815 (Holy Alliance): In the wake of the Seventh Coalition’s victory over Napoleon (Waterloo Campaign), Tsar Alexander I of Russia advocated a ‘Holy Alliance’ among the Great Powers to restrain the forces of liberalism and secularism. He was joined in this endeavor by Prussia and Austria, and the alliance soon grew to embrace most of the Christian kingdoms of Europe. However, the Holy Alliance was undermined by the conflicting interests of its members and collapsed with the death of the Tsar in 1825.
