Was Crocodile stronger at Marineford? Or was he holding back in Alabasta?

 During the Alabasta arc, Crocodile displayed a level of power that was initially considered overwhelming by the Straw Hat Pirates. He possessed the Logia-type Devil Fruit called the Suna Suna no Mi (Sand-Sand Fruit), which granted him the ability to control and transform into sand. He had a reputation as a Shichibukai and controlled the desert kingdom of Alabasta from the shadows. His strength was showcased through his battles with Luffy and others. At Marineford, Crocodile was present as part of the war that took place at Marine Headquarters. While he did participate in the battle, he didn't display the same level of dominance as some other powerful characters present. This has led fans to speculate that he might not have been as strong as initially portrayed in Alabasta. It's important to note that power scaling and character abilities can be subject to interpretation and development by the author. Oda often keeps details deliberately open-ended to keep the story intriguing.

Who was the world's first king?

 the world’s first empire more than 4,000 years ago in Mesopotamia King Sargon of Akkad—who legend says was destined to rule—established

His name signified "genuine ruler," and Sargon of Akkad (obscure 2279 B.C.) exploited that assumed authenticity to lay out the world's first domain around 2330 B.C. in Mesopotamia, the ripe land between the Tigris and Euphrates Rivers. He and his replacements gave to the world an idea of force that elaborate more than military strength. They instructed submission not just by winning fights and striking apprehension in their enemies, yet additionally by forcing request, apportioning equity, and filling in as natural delegates of divine beings their subjects feared and loved.

As indicated by legend, Sargon of Akkad was brought into the world in confidential to a priestess mother who set him hapless on a stream, where he was found by the normal worker who raised him. In his childhood, Sargon was visited by Ishtar-goddess of want, ripeness, tempests, and fighting who cherished him. Roused by her, he rose from lack of definition and overwhelmed the world. The story appears to be plainly planned to show that Sargon was qualified for rule Mesopotamia, but humble his starting points. (Who was the most influential lady in antiquated history?)

Akkadians had for quite some time been students of the Sumerians, whose human advancement only south of Akkad in Mesopotamia had been flourishing for a thousand years. They advanced much from the Sumerians prior to arising first as their opponents and eventually as their rulers. That interaction, wherein aggressive individuals at the edges of a laid out society turned into its lords, would be rehashed since forever ago by incredible realm manufacturers, including the Romans who vanquished Greece and the Mongols who overran China.

Before Sargon took power, the noticeable Sumerian city-territories of Ur and Uruk battled with Kish to their north, in Akkad, close to cutting edge Baghdad. Sargon started his ascent as a cupbearer to the ruler of Kish, whom he ultimately ousted. He then, at that point, drove troops against the extraordinary opponent ruler toward the south, Lugalzagesi, who instructed all of Sumer. Hatreds among Sumerian city-states might have hampered Lugalzagesi in his battle against Sargon, who caught him and set a burden around his neck. A celebratory engraving later flaunted that Sargon prevailed in 34 fights on his walk to the Persian Gulf, where he "washed his weapons in the ocean." (See how the regal burial chambers of Ur uncover Mesopotamia's brilliant quality.)

Formation of a domain

Sargon sent Akkadian lead representatives to manage Sumerian urban areas and destroy protective dividers. He left the Sumerian religion set up yet made Akkadian the authority language of all Mesopotamia. By bringing down physical and phonetic obstructions and binding together his domain, he advanced trade both inside Mesopotamia and past. A flourishing exchange with India brought.
