The Lion and the Rose

In English history, one of the major events was the Wars of the Roses. It was fought between the Yorks (white rose) and Lancasters (red rose), two cadet branches of the House of Plantagenet (three lions). Eventually, the Tudors won the war by defeating Richard III at the Battle of Bosworth Field. But what if the Yorkists had the throne right off the bat, instead of the Lancasters? Then it would no longer be the Wars of the Roses. It would be the Wars of the Lion and the Rose.

History
Assuming Yorkist victory, they would be the Plantagenets, and Lancasters would be no more. England would continue to have its problems with France, but claiming the throne of France would be less prevalent. Several butterflies are caused by this change in history. Aragon and Castile never become a single, unified kingdom. Aragon instead united with a weaker France. Nations like the Kalmar Union and the Holy Roman Empire still exist, although the latter slowly becomes the nation of Germany. The colonization of the Americas, called Atlantis (North America) and Amazonia (South America), is also different.

Nations
Superpower nations include Russia, France, and the United States, followed closely by the United Kingdom and Japan. The world is divided into two large blocs, led by the GOC (Global Organization for Cooperation) and the Paris Pact. A third bloc is the group of non-aligned nations, which consists of the Commonwealth, the Middle Eastern Co-Prosperity Sphere, and other nations.

Technology
Technology is a few years ahead of ours, although the general landscape is mostly the same. However, space exploration is still a major objective of nations. Moon landings have happened more than in OTL, and research in sustaining life on the moon is ongoing and even conducted by governments.
