This document discusses the unification of Italy and Germany in the 19th century. It describes how Italy was unified through the efforts of Giuseppe Mazzini, Count Cavour, and Giuseppe Garibaldi who helped bring together the various kingdoms and city-states of the Italian peninsula into a single nation through revolutionary and military actions against foreign rulers. Similarly, it outlines how Germany was unified through the diplomacy and warfare of Otto von Bismarck, including Prussia's wars against Denmark, Austria, and France which consolidated the northern German states under Prussian leadership and inspired the southern German states to also join, culminating in the establishment of the German Empire in 1871.
