Brazil has one of the largest and fastest growing economies in the world, and is predicted to become one of the top five economies globally in the coming decades. It has a large industrial sector producing automobiles, steel, and aircraft. Agriculture is also important, with Brazil being a top global producer of grains and soybeans. Historically, Brazil's economy relied on exports of gold, coffee, sugar, and raw materials, and used slave labor until the 19th century. It has since diversified and now has hundreds of trade partners.
