The Roman Republic was a sister republic of the First French Republic that existed from 1798 to 1799. It was proclaimed on 15 February 1798 after Louis-Alexandre Berthier, a general of the French Revolutionary Army, had occupied the city of Rome on 11 February. It was led by a Directory of five men and comprised territory conquered from the Papal States. The Roman Republic immediately incorporated two other former-papal revolutionary administrations, the Tiberina Republic and the Anconine Republic. It proved short-lived, as Neapolitan troops restored the Papal States in October 1799.

Women's rights are the rights and entitlements claimed for women and girls worldwide. They formed the basis for the women's rights movement in the 19th century and the feminist movements during the 20th and 21st centuries. In some countries, these rights are institutionalized or supported by law, local custom, and behavior, whereas in others, they are ignored and suppressed. They differ from broader notions of human rights through claims of an inherent historical and traditional bias against the exercise of rights by women and girls, in favor of men and boys.

World War II, or the Second World War, was a global conflict between two coalitions: the Allies and the Axis powers. Nearly all of the world's countries participated. Tanks and aircraft played major roles, the latter enabling the strategic bombing of cities and delivery of the only nuclear weapons used in war. World War II was the deadliest conflict in history, causing the death of 60 to 75 million people. Millions died as a result of massacres, starvation, disease, and genocides, including the Holocaust. After the Allied victory, Germany, Austria, Japan, and Korea were occupied, and German and Japanese leaders were tried for war crimes.

A drilling rig is an integrated system that drills wells, such as oil or water wells, or holes for piling and other construction purposes, into the earth's subsurface. Drilling rigs can be massive structures housing equipment used to drill water wells, oil wells, or natural gas extraction wells, or they can be small enough to be moved manually by one person and such are called augers. Drilling rigs can sample subsurface mineral deposits, test rock, soil and groundwater physical properties, and also can be used to install sub-surface fabrications, such as underground utilities, instrumentation, tunnels or wells. Drilling rigs can be mobile equipment mounted on trucks, tracks or trailers, or more permanent land or marine-based structures. The term "rig" therefore generally refers to the complex equipment that is used to penetrate the surface of the Earth's crust.
