Sounds like the Hapsburg dynasty of Austria-Hungary, although Pope Gregory did not live 500 years.

Thanks so much!!

The dynasty you are referring to is the Habsburg dynasty. To arrive at this answer, we can break down the question into separate components and search for the relevant information.

1. First, let's identify the pope who supported this dynasty. The question mentions "Pop Gregory," which is likely a typo. Let's assume it refers to Pope Gregory. To find which pope was in power during the 15th to 20th centuries, we can perform a quick search for a list of popes during this time period.

2. Once we know the name of the pope, we can then search for the emperor who was supported by him. In this case, the question specifies that Rudolph I was the first emperor. By combining the name of the pope and the emperor, we can search for any connections between them.

After conducting this search, we will find that Pope Gregory XIII (13th) was the pope during the 16th century. During his papacy, he supported the House of Habsburg, and Rudolph I of Habsburg was indeed the first emperor of the Habsburg dynasty. Therefore, it can be concluded that the Habsburg dynasty was supported by Pope Gregory with Rudolph I as its first emperor, spanning from the 15th to 20th centuries.
