Most of those who left Ireland arrived in Buenos Aires attracted by the possibility of better living conditions, as the economic, social and political conditions in Ireland at the time were quite poor, but the emigrants came from counties and social segments in which the economic conditions were not the worst (Westmeath, Longford, Offaly, Wexford). Others, in turn, left after receiving favourable descriptions of the country from friends and family who had already arrived in Argentina. The real or perceived possibility to becoming landowners in the Río de la Plata region (Argentina and Uruguay) and consequently joining the South American landed gentry, was the most important factor attracting thousands of young men to the area. Others had arrived earlier as merchants, artisans and mercenaries, such as William Brown, who fought for the cause of Argentine independence and the Argentine war against Brazil. For Irish immigrants, the new lands of the Southern Cone of South America brought further interest for immigration to purchase large land tracts for bargain prices, working first as labourers, then in "halves" or "thirds" in the sheep-farming business, and finally renting and purchasing land.
