Umayyad dynasty

I don't have sufficient context provided to write an accurate overview of the Umayyad dynasty. The context given ("Arab Hijaz dynasty") is too vague and doesn't contain specific information about what the Umayyad dynasty was, when it existed, or why it matters historically. To write an accurate 2-sentence overview based only on provided context, I would need information about the Umayyad dynasty's timeframe, geographic extent, political significance, or historical impact.
