Answer:
- Austria-Hungary was responding to a direct attack against members of its royal family. Austrian Archduke Franz Ferdinand and his wife were assassinated by terrorists in Sarajevo, Serbia. Austria-Hungary held Serbia responsible.
- Russia mobilized troops in keeping with an alliance it had with Serbia, offering them protection against the threatened military action by Austria-Hungary.
More details:
Various systems of alliances were put in place before World War I. The two main alliance systems were the Triple Entente, which had Britain, France and Russia as allies, and the Triple Alliance, which had Germany, Austria-Hungary, and Italy as allies. There were also other alliances, such as Russia taking on recently independent Serbia as an ally, as both had ethnic Slavic populations.
So here's how the start of World War I happened. When the Austrian prince and his wife were assassinated in Serbia, the Austrian government threatened the nation of Serbia with retaliatory action (even though the assassination was carried out by a terrorist group, not the Serbian government). Russia responded to Austria's threat, because Russia was bound to protect its Slavic ally, Serbia. Germany responded to the mobilization of Russian troops, and when Germany declared war on Russia in 1914, they implemented a military plan (the Schlieffen Plan), which assumed war would mean they'd have to take on all members of the Triple Entente alliance. So as soon as Germany declared war on Russia, they sent troops to go attack France. That pulled France and Britain into the war immediately as well, and the war spread and became a global conflict.

Answer:
The Mexican–American War, also known in the United States as the Mexican War and in Mexico as the Intervención Estadounidense en México, was an armed conflict between the United States and Mexico from 1846 to 1848. It followed in the wake of the 1845 U.S. annexation of Texas, which Mexico still considered Mexican territory since the government did not recognize the treaty signed by Mexican General Antonio López de Santa Anna when he was a prisoner of the Texian Army during the 1836 Texas Revolution. The Republic of Texas was defacto an independent country, but most of its citizens wished to be annexed by the United States. Domestic sectional politics in the U.S. prevented that since Texas would have been a slave state, upsetting the balance of power between northern free states and southern slave states. In the 1844 United States presidential election, Democrat James K. Polk was elected on a platform of expanding U.S. territory in Oregon and Texas. Polk advocated expansion by either peaceful means or by armed force, with the 1845 annexation of Texas as furthering that goal. For Mexico, this was itself a provocation, but Polk went further, sending U.S. Army troops to the area; he sent also a diplomatic mission to Mexico to try to negotiate sale of territory. U.S. troops' presence was provocative and designed to lure Mexico into starting the conflict, putting the onus on Mexico and allowing Polk to argue to Congress that a declaration of war should be issued. Mexican forces attacked U.S. forces, and the United States Congress declared war.
