Cities.—The chief seaport is Buenos Aires, the capital and largest city, with a population of 1,315,000 in 1911. La Plata lies twenty-five miles to the southeast of the Federal capital, and, although founded in only 1882, already numbers 80,000 inhabitants. A canal joins it to the vast docks of Ensenada.

Córdova (53,000), nearly in the center of the state, is the seat of the chief observatory of the Republic.

Rosario (135,000), on the right bank of the Paraná, more than two hundred miles up from the La Plata inlet, is a substantially built town, and a great outlet of the animal produce of the interior plains.

Tucuman (55,000) and Salta in the northwestern mountain region, and Mendoza (32,000) at the eastern base of the Andes, where they are crossed to enter Chile, with Corrientes (18,000) on the Paraná, are other important places.

Buenos Aires (bwā´nōs ī´rez; Sp. pron. bwā´nōs ī´res; Eng. pron. usually Bonos Ai´rez) stands on the right bank of the Plata, which here, at a distance of one hundred and fifty miles from the open sea, is twenty-eight miles across.

The city is partitioned into blocks of about one hundred and fifty yards square. The streets are regularly laid out at right angles to each other and well lighted. Many are planted with trees, and there are numerous open squares and several fine parks, the most famous being Palermo Park (eight hundred and forty acres). The main buildings are the Roman Catholic Cathedral, the chapel of Santa Felicitas, the Casa Rosada, or Government House, the university, the Opera House, and various government and municipal buildings. Much of the town has lately been rebuilt on European lines. It is the terminus of six railway lines, and has excellent street car, cable, and telephone services. There are manufactories of furniture, machinery, carriages, leather, hats, textiles, boots, tobacco, liquors, etc., and the trade is very large.

An elaborate system of harbor works was carried out between the years 1887 and 1895 at a cost of twenty million dollars; it includes an advanced river wall, a north and south basin, and a series of four docks, which connects two channels of the Rio de La Plata, and so brings large vessels up to the wharfs. About half of the inhabitants are of European birth or descent. Among the Europeans the vast majority are Italian; the rest are principally Spanish, French and British. Newspapers are published in French, English, Italian, and German, as well as in Spanish.

History.—The river La Plata was visited by the Spaniards in 1516, and the country was [674] colonized in 1535, when Buenos Aires was founded. For many years the country was regarded as a part of Peru. The progress of the colony was not more hindered by the bloody wars which prevailed with the natives for a hundred years than by unwise legislation at Madrid.

In 1776 Buenos Aires became the capital of a new viceroyalty. In 1806 that capital was occupied by a British force under General Beresford, but the town was soon besieged and compelled to surrender. In 1808 the British forces under Whitlock assaulted the town, but after very severe loss were themselves compelled to capitulate.

In 1810 the colonists founded a local provisional government. A sanguinary war for independence followed, which did not cease till 1824. Spain acknowledged the independence of the country in 1842. The first half-century of Argentine autonomy was much disturbed by revolutions.
