It turns out that Scotland will be staying in the United Kingdom, but why did Scotland want to break away in the first place? Partially, it had to do with Scotland's long-standing rivalry with England.
Before the neighboring countries were joined together by the Acts of Union in 1707, their history was marked by a slew of battles. Although the wars ended, their rivalry continued into to the modern era. Even with a "No" vote against independence winning, Scotland's general distaste for the English is unlikely to fade.
