What was the long-term impact of martin luther's break from the catholic church? what do we see today as a result of his "revolution"?

The long-term impact of the break from the Catholic Church was the rise of Protestantism, a denomination within Christianity.

People who followed Martin Luther would establish communities which later formed the protestant Churches and people who remained loyal to the Catholic Church ensured the continued existence of the Church.

Today we can still see the split, for example, Southern Europe is mostly catholic and northern Europe is mostly Protestant.
