One of the causes of the Black death was the involvment of traders and merchants coming from sea and bringing the disease with them. It soread easily due to poor hygiene at the time and not so great medical practices. It killed around 50% of Europes population and and had around a 99-100% fatality rate.

The great famine was caused by a disease that destroyed the potato crop which happened to be one of the more available foods at the time. About a million died in result of this and people began to leave Ireland immigrating to places such as the us, australia, britain or canada.

Henry IV did not create the Estates General. That institution had developed already in medieval France, fell out of use, but then was revived during the latter half of the 16th century, a couple decades before Henry IV came to the throne.
Henry IV did not oppress the French people but sought to build roads and improve agriculture for the betterment of France and to build the loyalty of the people to his rule.
He did overthrow the previous ruler (Henry III), but not in "totalitarian fashion." After winning the "War of the Three Henrys" in order to become king, Henry sought to bring France to peace after religious warfare. He had been Protestant but converted to Catholicism for the sake of national peace, while at the same time extending legal protections to the Protestant minority.
Under Henry IV's rule, the central government did not control "almost every aspect of life." He worked hard to consolidate and centralize power for his government, but he was not yet what we would call an "absolute" ruler.
