The Pernambucan started in the province of Pernambuco during the year 1817. This revolution was caused for many reasons. First of all, it was marked by the decline of sugar production rates and the influence of the independence of the Spanish colonies all over South Amercia and also the presence of the Portuguese Royal family contributed to its outbreak.
Merchants and plantation owners were the only people who took advantage of the monarch's presence. However, other citizens were not satisfied with the Royal Family's stay since they did not agree with the politics of the monarch, John VI. The rebellion was carried out by planters who did not agree with the restrictions imposed by the colonial control of economy and who believed in the ideas of freedom which came from French philosophers.
The Pernambuco revolution of 1817 was influenced by the transderence of the Royal Family to Rio de Janeiro due to the high expenses and impositions brought by the Royal Family (the Government of Pernambuco was obliged to send large amounts of money to Rio de Janeiro to pay for wages, food, clothes and royal parties, which made it difficult to deal with local problems). In addition, together with the climate of revolt over the exploitation of Portugal to Brazil, it has generated a series of revolts throughout the country, such as the outbreak of the Pernambuco revolution. Thus, the movement was motivated by the dissatisfaction of the Pernambucans due to the economic crisis and the high taxes instituted by D. João VI.
Opposing sides were dug into trenches, which led to higher casualties and poor conditions for soldiers but they could rarely advance because of improved technologies such as machine guns which gave a tactical advantage to defensive forces and artillery.
