Under the title of “Journeys to the ancient kingdoms of the Persian Gulf” we present a series of thematic trips with which we aim to learn about both the past of the important and sometimes little-known civilizations that developed in this area, as well as its present that sometimes leans towards a futuristic world and sometimes opts for conservatism while maintaining ancient traditions. With the first of these trips to “Iraq, ancient Mesopotamia” we will learn about the ancient Sumero-Akkadian and Assyrian-Babylonian civilizations. The second trip is the one we present here, we will discover the ancient kingdoms that were in contact with these traditional Mesopotamian civilizations, but which are very unknown; thus, we will travel to Oman and the Arab Emirates, where the ancient Magan was located, and to Qatar and Bahrain, where the ancient kingdom of Dilmun existed. On a third trip we will go to the south of Iran to discover the kingdoms of Elam and Marhashi and, finally, on a fourth and final trip we will go to Pakistan to visit the Indus Valley, seat of the Meluhha kingdom. But focusing on this trip, the objective is to get to know a little better two important kingdoms that, since the 3rd millennium BC. acted as intermediaries between the Mesopotamian cultures of the north and the cultures of the Indus Valley of the south, linking the two ends of the Persian Gulf and the Gulf of Oman through a very important commercial network that was maintained for millennia and that, to some extent, still works today. The first of these ancient kingdoms is Magan, located in the current country of Oman and part of the United Arab Emirates. Its first mention is in a Sumerian text from 2600 BC and from that time until 550 BC, its importance was that of being the most important exporting center of diorite, copper and incense to Mesopotamia and other products from more distant kingdoms such as that of Meluhha. The second kingdom that we will know is Dilmun, located in Bahrain, which since the end of the 4th millennium BC acted as the main port of the commercial network that linked Mesopotamia with Meluhha. But also, in Mesopotamian mythology, Dilmun was a sacred and extremely rich place where Sumerian stories locate nothing less than the paradise that would later also be described in the Bible. Ancient disappeared kingdoms, precious goods, legendary myths, lost paradises... all this and much more awaits us on a unique journey where, in addition to the past, we will also encounter a spectacular, modern and traditional present and landscapes that combine steep mountains with idyllic beaches and dune deserts and with the Persian Gulf Sea as the backbone.
