His was the second-longest documented pontificate, which lasted 26 years and 168 days; only Pope Pius IX (1846-1878) who served 31 years, has reigned longer. Pope John Paul II is the only Slavic or Polish pope to date and was the first non-Italian Pope since Dutch Pope Adrian VI (1522-1523).

It is widely held that he was instrumental in ending communism in his native Poland and eventually all of Europe.
