History

Breakfast before the 1800s was usually just toast or some variation of gruel or porridge and the main meal was dinner. Peasants (which were the majority in every country) had dinner around noon, after six or seven hours of work.

Then, in the late 1700s and the 1800s, people began to work farther from home, and the midday meal had to become something light, just whatever they could carry to work (lunch). They began to eat dinner (the main meal) in the evening.
