The Duchy of Brunswick was one of the places of origin of many German immigrants, all in search of opportunities for a better life in Brazil. Many of them have taken as their destination, mainly, the colonies Blumenau and Dona Francisca (now Joinville). Gradually, the German immigrants of various origins settled in territorial regions near these two colonies.
Brunswick was never Great enough to make an important part in the politics of Germany. Brunswick owed debts to the British, who had come to their aid during wars in Germany. To pay your debt, Brunswick were sent soldiers o America during the American Revolution to fight for the British. Some of those German soldiers, they did not return home, but began new lives in America (1776).
During Napoleon's invasion by Germany, Brunswick takes advantage of the Prussians. In 1806, Napoleon dissolved the Duchy of Brunswick and became attached to the Kingdom of Westphalia, which Napoleon arranged for his brother Jerome. This lasted until 1815, when the Vienna Treaty dissolved the Kingdom of Westphalia and removed the French control of German lands. Brunswick became then an independent Duchy again. The Revolution swept through Brunswick before 1830, but the Duke Wilhelm restored order after 1830, and new reforms were put in place.
In 1844, the State joined the Prussian Customs Union, which allowed trade to be conducted between the Prussian provinces.
In 1871, Brunswick joined the newly created German Empire. After World War I, the last Duke deposed and Brunswick became a free State within the Weimar Republic in 1919. After World War II, was in the British zone of occupation until 1946 when Brunswick became part of the modern State of Niedersachsen (Lower Saxony) along with Hanover, Oldenburg, and Schaumburg-
The population of Brunswick was composed of Saxons, who spoke originally Plattdeutsch (low German). The area to the North was populated more intensely, because the South was mountainous. Less than a quarter of the population had a role in farming or forestry. The main crops were wheat, beets and potatoes. The waste products of beets were used for the livestock industry.
The rights of primogeniture in Brunswick allowed the oldest son inherited the family land rather than split it up among all the surviving heirs. But this was not made universal throughout Brunswick. Some districts gave the land to the younger male.
In the early 1800s, the population grew due to the expectation of better life. This created more landless peasants seeking jobs. The Union's limitations were imposed to slow the growth of the population, but this only increased the number of illegitimate births.
The Emigration was high during the 1840s, but dropped out in the 1850s. The limitations of Union was repealed in the 1860s, and joints increased. In later years 1800s, some inhabitants migrated to other parts of Germany.
