Problem: Following the death of Grand Prince Igor in 945, his wife Olga ruled as regent in Kiev until their son Sviatoslav reached maturity (ca. 963). His decade-long reign over Rus' was marked by rapid expansion through the conquest of the Khazars of the Pontic steppe and the invasion of the Balkans. By the end of his short life, Sviatoslav carved out for himself the largest state in Europe, eventually moving his capital from Kiev to Pereyaslavets on the Danube in 969. In contrast with his mother's conversion to Christianity, Sviatoslav, like his druzhina, remained a staunch pagan. Due to his abrupt death in an ambush in 972, Sviatoslav's conquests, for the most part, were not consolidated into a functioning empire, while his failure to establish a stable succession led to a fratricidal feud among his sons, which resulted in two of his three sons being killed.
What year was Sviatoslav's empire consolidated?

Problem: The Napoleonic Wars were therefore ones in which Britain invested large amounts of capital and resources to win. French ports were blockaded by the Royal Navy, which won a decisive victory over a Franco-Spanish fleet at Trafalgar in 1805. Overseas colonies were attacked and occupied, including those of the Netherlands, which was annexed by Napoleon in 1810. France was finally defeated by a coalition of European armies in 1815. Britain was again the beneficiary of peace treaties: France ceded the Ionian Islands, Malta (which it had occupied in 1797 and 1798 respectively), Mauritius, St Lucia, and Tobago; Spain ceded Trinidad; the Netherlands Guyana, and the Cape Colony. Britain returned Guadeloupe, Martinique, French Guiana, and Réunion to France, and Java and Suriname to the Netherlands, while gaining control of Ceylon (1795–1815).
When was Napoleon finally defeated?

Answer: 1815


Problem: In January 1957, the US adopted the Eisenhower Doctrine and pledged to prevent the spread of communism and its perceived agents in the Middle East. Although Nasser was an opponent of communism in the region, his promotion of pan-Arabism was viewed as a threat by pro-Western states in the region.

Also in January, the elected Jordanian prime minister and Nasser supporter Sulayman al-Nabulsi brought Jordan into a military pact with Egypt, Syria, and Saudi Arabia.
