Elizabeth II was not only Britain's longest ever-reigning monarch, she will also be remembered as one of the country's most beloved sovereigns.

What will his promises to modernize the institution mean? And how will he handle the ongoing crises presented by younger brother Prince Andrew, and youngest son Prince Harry?
