Question: Classical music is art music produced or rooted in the traditions of Western music, including both liturgical (religious) and secular music. While a similar term is also used to refer to the period from 1750 to 1820 (the Classical period), this article is about the broad span of time from roughly the 11th century to the present day, which includes the Classical period and various other periods. The central norms of this tradition became codified between 1550 and 1900, which is known as the common practice period. The major time divisions of classical music are as follows: the early music period, which includes the Medieval (500–1400) and the Renaissance (1400–1600) eras; the Common practice period, which includes the Baroque (1600–1750), Classical (1750–1820), and Romantic eras (1804–1910); and the 20th century (1901–2000) which includes the modern (1890–1930) that overlaps from the late 19th-century, the high modern (mid 20th-century), and contemporary or postmodern (1975–2015) eras.[citation needed]

Question: South West Africa became known as Namibia by the UN when the General Assembly changed the territory's name by Resolution 2372 (XXII) of 12 June 1968. In 1978 the UN Security Council passed UN Resolution 435 which planned a transition toward independence for Namibia. Attempts to persuade South Africa to agree to the plan's implementation were not successful until 1988 when the transition to independence finally started under a diplomatic agreement between South Africa, Angola and Cuba, with the USSR and the USA as observers, under which South Africa agreed to withdraw and demobilise its forces in Namibia. As a result, Cuba agreed to pull back its troops in southern Angola sent to support the MPLA in its war for control of Angola with UNITA.

Answer:
1988
