Well aside from Argonians, Hist trees are also very important parts of Black March. They're basically sentient trees that are usually credited with being the first inhabitants of Tamriel. The Argonians have very close connections to them, and sometimes call themselves "people of the root," which also accounts for any mention of "Roots" in Argonian names. Argonians lick the sap of the Hist tree to get visions from them and that's how they communicate. But if any other race tries to do this, they just get extremely powerful and violent hallucinations.
The Hist speak more directly to each other (they're all said to connect at the root) and to the An-Xileel, a political party that wanted Black Marsh's independence from the Empire. The Hist were apparently able to foresee the Oblivion Crisis before it happened, and thus summoned all the Argonians across the Empire to return to Black Marsh. Through the An-Xileel, the Hist spoke of the Daedra that would come flooding out of the Oblivion Gates and ordered Argonians to attack the hell out of the gates. They attacked with such unyielding ferocity that Mehrunes' generals and lieutenants had to close the Oblivion Gates themselves to keep the Argonians out. Sooo because of that, the Hist and An-Xileel are almost always recognized as the reason Black Marsh survived the Oblivion Crisis. And because they did it all by themselves, that's how the Empire lost its foothold in Black Marsh and the lizard people got their independence.
Source is this book "The Infernal City," which basically detailing events that transcribed directly after the events of Oblivion. Also the main story is about this floating city of death, that's pretty cool, too.
