The revolutionary wave of the 1830s confirmed two major political developments. First, it widened the split between the West and the East already evident after the revolutions of 1820. Britain and France were committed to support cautiously liberal constitutional monarchies both at home and in Belgium.
On the other hand, Russia, Austria, and Prussia were more firmly committed than ever to counterrevolution. In 1833 Czar Nicholas I, Metternich, and King Frederick William III formally pledged their joint assistance to any sovereign threatened by revolution.
