What event during shakespeare's lifetime probably his career as a dramatist?

The correct answer is plague. Health regulations of the time in London urged that all the playhouses had to be closed which put the people employed by the theatre industry out of work. Shakespeare, however, started writing poetry. Before this time, Shakespeare had already written a few plays. His poems were a huge hit and they have made Shakespeare very rich and better known as a writer. Both the quality and quantity of his work improved drastically. We can assume that his partners allowed him to spend  more time writing because they knew from his poems that his work will be popular.
