What struggles did Copernicus have in life?

Answer 1

We know very little what events Nicolae Copernicus viewed as "struggles," as he never wrote much about his inner thoughts. We can only speculate.

Amongst events that may have made his life difficult for Nicolae:

1) His father died when he was 10. His maternal uncle then became his benefactor and major employer.

2) When Nicolae uncle attempted to have him installed in a church post, the order (for reasons still unknown) refused. Nicolae then went to Rome to study canon law.

3) It took him seven years to get a degree while in Italy, indicating a lack of devotion to study in that specific field. Again, we don't know the details.

4) During the time he was an adminstrative assistant to his uncle, the city of Warmia was often under attack from Teutonic Knights.

5) Despite urgings from his friends and co-workers, Nicolae refused to publish his heliocentric ideas, fearing attacks for "the novelty and incomprehensibility of his theses."
