In sports, a dynasty refers to a prolonged period where a single team or athlete dominates the championship or top tier of a sport for multiple consecutive years (e.g., the New England Patriots in the NFL, Manchester City in the Premier League, or Red Bull Racing in Formula 1). An era of parity refers to a competitive landscape where multiple different teams or athletes have a realistic chance of winning championships from year to year, resulting in high unpredictable outcomes and frequent turnover at the top.
