The indigenous population in Brazil was sparsely scattered when Portuguese explorer Pedro Cabral arrived in 1500, marking the beginning of Brazil's colonial period. Over the next two centuries, other European powers like Britain and France attempted to establish colonies in Brazil, drawn by its abundant natural resources and vast untouched lands. In modern times, Brazil faced challenges hosting the 2016 Olympics in Rio de Janeiro, as the Joao Havelange stadium constructed for the athletics events was deemed unsafe and indefinitely closed until structural issues could be resolved.
