In 1887, Francesco Crispi became Prime Minister and began focusing government efforts on foreign policy. Crispi worked to build Italy as a great world power through increased military expenditures, advocacy of expansionism and trying to win the favor of Germany. Italy joined the Triple Alliance which included both Germany and Austria-Hungary in 1882 and which remained officially intact until 1915. While helping Italy develop strategically, he continued "trasformismo" and became authoritarian, once suggesting the use of martial law to ban opposition parties. Despite being authoritarian, Crispi put through liberal policies such as the Public Health Act of 1888 and establishing tribunals for redress against abuses by the government.
