Document 2: Muammar Gaddafi: Following his defeat in the civil war, Gaddafi's system of governance was dismantled and replaced under the interim government of the NTC, who legalised trade unions and freedom of the press. In July 2012, elections were held to form a new General National Congress (GNC), who officially took over governance from the NTC in August. The GNC proceeded to elect Mohammed Magariaf as president of the chamber, and then voted Mustafa A.G. Abushagur as Prime Minister; when Abushagar failed to gain congressional approval, the GNC instead elected Ali Zeidan to the position. In January 2013, the GNC officially renamed the Jamahiriyah as the "State of Libya".
Document 3: Galicia (Spain): Christianity is the most widely practised religion in Galicia, as it has been since its introduction in Late Antiquity, although it lived alongside the old Gallaeci religion for a few centuries.

Document 4: Somalis: On 15 October 1969, while paying a visit to the northern town of Las Anod, Somalia's then President Abdirashid Ali Shermarke was shot dead by one of his own bodyguards.

The putsch was spearheaded by Major General Mohamed Siad Barre, who at the time commanded the army.

Near the Old Town is the district of Calenberger Neustadt where the Catholic Basilica Minor of St. Clemens, the Reformed Church and the Lutheran Neustädter Hof- und Stadtkirche St. Johannis are located.
