And so whenever you have something this long lasting, you can imagine the social and the political structures evolved over time. But let's begin with the period when it was a kingdom. Because even then, there were some things that were noteworthy, and some social and political structures that continued into the Republic period and even when it was an empire. So one interesting thing is that when we typically think of kings, we think of it as being dynastic, that if I am king, then my oldest son, or maybe in certain cultures, my oldest daughter might become king or queen. But it turns out that many of the, especially the early kings of the Roman kingdom, were actually elected. They had a lot of power. All the power resided in them.
