Judging by old maps, the configuration of the Caspian Sea was not at all the same as it is now. It was much larger than the modern size and took in a lot of rivers from the east, which do not exist now. In addition, from the west, the Caspian Sea had a water connection with the Black Sea, this place is now called the Kuma-Manych depression. She is also present on the cards.
The Caspian was once the size of two Black Seas. What sources filled it like this, provided there was no connection with the outer sea? Is the Volga and the very rivers of the inner basin?
Let's take a look at the map "Atlas Russicus mappa una generali et undeviginti specialibus vastissimum imperium Russicum adjacentibus regionibus secundum leges geographicas":
What is unusual about this map of an unidentified edition year? At first glance, nothing. But there is unusualness here, and it is in the picture. More precisely, not even in the picture, but in the place that it fills. Pictures in such a place are inserted only when there is a completely uninformative section of the map. In other words, emptiness. Thus, starting from the eastern bank of the Volga, a desert called the Yaitskaya steppe opens. There are absolutely no settlements on it. From the north, this steppe has a border, which is mapped. How to understand such a geographical nuance? Why is life suddenly boiling on one bank of the Volga, and on the other it abruptly disappears?
Here, probably, we need to remember the very border between Europe and Asia, which was marked for some reason and in several variations:
Why did Lomonosov draw the border along the Volga and Pechora, when his opponents carried it along the Ural ridge? It turns out that everything is simple and both were right. Between the channel of the Volga and the Ural ridge there was a natural water barrier, the western coast of which was the border of Europe, and the eastern one - Asia. And with the disappearance of water in this water barrier, the very Yaitskaya steppe appeared and there was a need to demarcate the two parts of the world. And this water disappeared quite recently, by historical standards, only yesterday. And it is even possible, with some degree of error, to reconstruct this on a modern map:

If this took place at all, then it turns out that quite recently all the large and ancient cities of the Volga region and the Urals, including Perm (which did not fit on this map), were coastal cities and had access to both the Caspian basin and the North -Arctic Ocean. Where did all this go? Very simple. The same mudflow that covered the first floors of buildings also covered the outer sea traffic. The rivers of the inner basin began to accumulate and move along the border of those former straits to the lower side, i.e. to the Caspian, but their volume was not enough to raise the sea to its original height. The water balance was negative, and the Caspian Sea began to decrease every year, leaving behind saline steppes. Decreases now …
