Grand Duke Vladimir, Red Sun, Holy Baptist of Rus', who came to power by pagan law, and then autocratically threw pagan idols into the Dnieper. A sovereign who married a Byzantine princess and received the right to the royal (Caesar) title. Or rather, he won this right not only through the valor of his loyal squad, but also with his own sword. What is known about him, the greatest of the sovereigns of our history, who lived a thousand years ago? Much is known. And not only from domestic chronicles. Vladimir was known to the chroniclers of Europe and Asia, Byzantium and the Arab world. So there is enough information, truthful information, to clearly imagine the image of the sovereign-warrior, the sovereign-builder, who decisively turned to the Truth not only the Rus, but also hundreds of other tribes that lived on the land under his control. Vladimir's father, the great commander Svyatoslav, fought on equal terms with the Byzantine emperor. The Byzantine emperor found himself in debt to Vladimir. And the Grand Duke managed to force the ruler of the largest empire of that time to repay this debt in full. He achieved what was denied even to the Holy Roman Emperor.
