The northwestern part of the South Asia, including Punjab, was repeatedly invaded or conquered by various foreign empires, such as those of Tamerlane, Alexander the Great and Genghis Khan. Having conquered Drangiana, Arachosia, Gedrosia and Seistan in ten days, Alexander crossed the Hindu Kush and was thus fully informed of the magnificence of the country and its riches in gold, gems and pearls. However, Alexander had to encounter and reduce the tribes on the border of Punjab before entering the luxuriant plains. Having taken a northeasterly direction, he marched against the Aspii (mountaineers), who offered vigorous resistance, but were subdued.[citation needed] Alexander then marched through Ghazni, blockaded Magassa, and then marched to Ora and Bazira. Turning to the northeast, Alexander marched to Pucela, the capital of the district now known as Pakhli. He entered Western Punjab, where the ancient city of Nysa (at the site of modern-day Mong) was situated. A coalition was formed against Alexander by the Cathians, the people of Multan, who were very skilful in war. Alexander invested many troops, eventually killing seventeen thousand Cathians in this battle, and the city of Sagala (present-day Sialkot) was razed to the ground. Alexander left Punjab in 326 B.C. and took his army to the heartlands of his empire.[citation needed]

After the Civil War, population expansion, railroad construction, and the disappearance of the buffalo herds heightened military tensions on the Great Plains. Several tribes, especially the Sioux and Comanche, fiercely resisted confinement to reservations. The main role of the Army was to keep indigenous peoples on reservations and to end their wars against settlers and each other, William Tecumseh Sherman and Philip Sheridan were in charge. A famous victory for the Plains Nations was the Battle of the Little Big Horn in 1876, when Col. George Armstrong Custer and two hundred plus members of the 7th Cavalry were killed by a force consisting of Native Americans from the Lakota, Northern Cheyenne, and Arapaho nations. The last significant conflict came in 1891.

According to the census survey carried out between 15 June and 31 July 2004, Montevideo had a population of 1,325,968 persons, compared to Uruguay's total population of 3,241,003. The female population was 707,697 (53.4%) while the male population accounted for 618,271 (46.6%). The population had declined since the previous census carried out in 1996, with an average annual growth rate of −1.5 per thousand. Continual decline has been documented since the census period of 1975–1985, which showed a rate of −5.6 per thousand. The decrease is due in large part to lowered fertility, partly offset by mortality, and to a smaller degree in migration. The birth rate declined by 19% from 1996 (17 per thousand) to 2004 (13.8 per thousand). Similarly, the total fertility rate (TFR) declined from 2.24 in 1996 to 1.79 in 2004. However, mortality continued to fall with life expectancy at birth for both sexes increasing by 1.73 years.
