How was the path in terms of education for a small kid to follow in years so that he can become a LAWYER in 17th Century in Europe? (Mainly in The Holy Roman Empire).
Learning has not really changed over the centuries. What has changed are the words we use to describe what learning we are doing. Typically, as Steve Bird pointed out, a person would have to have some wealth to be taught formally. If your family was wealthy enough you had a private tutor that came and taught you who was usually highly educated in philosophy, faith or math (depending on the era). As the child grew into "college age" they would have attended what we call university today. In The Holy Roman Empire this was probably the University of Bologna. Founded in 1088, this school would have taught the students higher education in science, math, philosophy and law. What you should keep in mind though is that our idea of justice and the rule of law is not the same as what it was in the 1600s. Typically the church defined and ruled on matters of "law" which were based in faith, so in learning the faith which was taught by the schools you were learning the law you were bound by too.
