Input: Question: What year did the Scramble for Africa begin? Passage 1:In 945, Bosenbach had its first documentary mention when Otto I, Holy Roman Emperor, granted his faithful follower Franko a few landholds. To better describe where these landholds lay, both Reichenbach and Bosenbach were named. Either Franko or his heirs yielded these lands shortly after 945 to Saint Maximin's Abbey in Trier. Until about 1100, Bosenbach was listed time and again as being among the monastery's holdings. Territorially, Bosenbach belonged to the Imperial Domain (Reichsland) around Kaiserslautern and about 1130, it came to be held as a Palatine fief by the Counts of Veldenz. About 1282, the Amt of Bosenbach (Bosenbach, Niederstaufenbach and Friedelhausen) was held in common ownership by the Counts of Veldenz and the Waldgraves. Later, in the 14th and 15th centuries, the common ownership had ended and it was owned by the Waldgraves and Rhinegraves (one group). In 1595, through territorial trade, the Amt found its way back into the Duchy of Palatinate-Zweibrücken. From the years 1514, 1537 and 1578 come three Weistümer dealing with Bosenbach (a Weistum – cognate with English wisdom – was a legal pronouncement issued by men learned in law in the Middle Ages and early modern times; Weistümer is the plural).
 Passage 2:The 1880s saw an intense competition between the European powers for territories in Africa, a process known as the Scramble for Africa. The process culminated in the Berlin Conference of 1884, in which the European nations concerned agreed upon their respective territorial claims and the rules of engagements going forward. As a result of this France gained control of the upper valley of the Niger River (roughly equivalent to the areas of modern Mali and Niger). France had already conquered most of northern Algeria during the period 1830-47, incorporating it as an integral part of France. France occupied the area of modern Niger in 1900, declaring it a military territory, ruled originally from Zinder. Niger was originally included, along with modern Mali and Burkina Faso, within the Upper Senegal and Niger colony, however it was split off in 1911 and became a constituent of the federal colony of French West Africa (Afrique occidentale française, abbreviated AOF). In the meantime in Algeria France had been pushing south from the littoral region, conquering much of the Algerian Sahara in 1902. A boundary between French West Africa and French Algeria (i.e. what are now Algeria’s borders with Mauritania, Mali and Niger) was agreed on 7 June 1905 by the Commandant of Upper Senegal and Niger and the Military Commander of the Department de l'Oasis within French Algeria. The border was further defined by the Niamey Convention of June 1909.
 Passage 3:The discography of South Korean-born Australian recording artist Dami Im consists of five studio albums, two extended plays, ten singles, two album appearances, and four music videos. Im began her music career as a gospel singer in Korea and independently released her debut studio album, Dream, in 2010. She was the winner on the fifth season of The X Factor Australia in 2013, and subsequently received a contract with Sony Music Australia. Im released her self-titled second studio album in November 2013, which features selected songs she performed as part of the top twelve on The X Factor. The album debuted at number one on the ARIA Albums Chart and was certified platinum by the Australian Recording Industry Association (ARIA), denoting shipments of 70,000 copies. Additionally, the album also included Im's debut single "Alive", which topped the ARIA Singles Chart and was certified platinum. She became the first X Factor Australia contestant to follow up a number one single with a number one album on the ARIA Charts.
