Anyone who has a sibling knows that those relationships are always a little, shall we say, delicate. Sure, every so often you meet a pair of siblings who genuinely seem to like one another, but that’s not always the case.

Throughout history, there have been many famous stories of sibling rivalries that have ended families, kingdoms, and countries.

Among those stories, there have been quite a few particularly dramatic stories of rivalries between sisters.

Here are 10 of the most famous, and most dramatic, sister rivalries of all time.

Anne and Mary both had relationships with King Henry VIII, and Anne even ended up marrying the King.

Before he married Anne, King Henry VIII was married to Catherine of Aragon, the mother of their daughter, Mary.

After Henry married Anne, she gave birth to their daughter, Elizabeth.

Mary became Queen in 1553, but was always paranoid about her younger sister’s popularity. She even had Elizabeth banished and imprisoned. However, Mary died in 1558 without an heir.

Which meant… Elizabeth became Queen after all.

3. Venus and Serena Williams

While these songbird sisters are undoubtedly close, they’ve also maintained a professional rivalry over the years.
