Rio de Janeiro History

By the mid-16th century, French settlers called an island just off of Rio de Janeiro their home – but, not for long. A war was waged to expel the French from the land and to claim the property as theirs, in accordance with the Treaty of Tordesillas. The Portuguese population continued to expand in this area, as the French were pushed out of the land.

After Sao Paulo, Rio de Janeiro is the second largest city in Brazil. Rio de Janeiro was once the official capital of Brazil before it won its independence from Portugal and became its own country. It earned the title (which was taken from the city of Bahia) of being the capital during the year 1763, further allowing the popular city to expand beyond its original size. During this city’s early years, the main source of income for many settlers was sugar plantation and fishing. During the gold and diamond rush of the 18th century, the city’s population swelled when people heard of the discovery of the valuable commodities which were available in the neighboring town of Minas Gerais.

During the early 18th century, diamond and gold mining enticed European settlers to migrate into the city, bringing the population up to a whopping 24,000 by 1749. By the early 19th century, the Royal Family of Portugal fled their homeland in an attempt to escape Napoleon’s presence in Portugal. They settled in Rio de Janeiro, bringing along with them their servants and noblemen. Unfortunately, many lower class citizens within the community were ousted from their homes in order to make room for the royalty’s entourage.

Rio de Janeiro Population Growth

Today, this grand city continues its prosperous growth rate. Even after Rio de Janeiro lost its title of being the capital of Brazil in 1960, its population still swelled to an additional seven million people within sixty years of the announcement. Rio de Janeiro is still home to millions of citizens – with 3.9 million people added to the population census in 1950.

The city is home to more civilians than its neighboring suburban communities and continues its growth even today. In a 2010 population estimate by Demographia, Rio de Janeiro was the home of more than 11.6 million residents. Estimated projections for 2025 show the population will grow to at least 13.1 million people. By 2030, that number is projected to reach over 13.6 million citizens. Luckily, expansive amounts of land make additional urban development strategies a possible option for this swelling city.
