Mbh 2.12.2a

“Narada said,--‘O king of kings, I shall tell thee all that thou askest me about Harischandra, I shall presently tell thee of his high excellence. He was a powerful king, in fact, an emperor over all the kings of the earth. Indeed, all the kings of the earth obeyed his sway. O monarch, mounted alone upon a victorious car adorned with gold, that king by the prowess of his weapons brought the whole earth with her seven islands under his sway. And, O monarch, having subjugated the whole earth with her mountains, forests, and woods, he made preparations for the great sacrifice called the Rajasuya. And all the kings of the earth brought at his command wealth unto that sacrifice. All of them consented to become distributors of food and gifts unto the Brahmanas that were fed on the occasion. At that sacrifice king Harishchandra gave away unto all who asked, wealth that was five times what each had solicited. At the conclusion of the sacrifice, the king gratified the Brahmanas that came from various countries with large presents of various kinds of wealth. The Brahmanas gratified with various kinds of food and enjoyable articles, given away unto them to the extent of their desires, and with the heaps of jewels distributed amongst them, began to say,--King Harischandra is superior to all kings in energy and renown.--And know, O monarch, O bull of the Bharata race, it was for this reason that Harischandra shone more brightly than thousands of other kings. The powerful Harischandra having concluded his great sacrifice, became installed, O king, in the sovereignty of the earth and looked resplendent on his throne. O bull of the Bharata race, all those monarchs that perform the sacrifice of Rajasuya, (attaining to the region of Indra) pass their time in felicity in Indra’s company. And, O bull of the Bharata race, those kings also that yield up their lives without turning their backs on the field of battle attain to the mansion of Indra and live in joy with him.
