Sometimes the Caddo or a branch of them are called Tejas or Teyas in older accounts.
Some of their site is pretty, well, interesting in their claims:
"1500) The Blue Woman / The Blue Water Woman
The Creator prepares her for her fist her journeys to Tejas and appears to the Great Council of Chiefs pictured here - she converts and teaches Christianity to the Tribal Nation and telling the old stories of the Nation, bringing revelation to the medicine lodges and baptizing over 30,000 Tejas. She is the Matron Saint of the Tribal Nation. These reports start to reach Spain in 1689 records of her visits to the hidden kingdom of the Tejas Nation - Maria de Jesus Azle de los Agreda."
Historian Rolando Romero had this to say about Agreda. She was a Spanish nun who never visited Texas, only imagined she had in visions.
http://www.sip.uiuc.edu/people/rromero/alamo.htm"One such story is that of the apparition of María de Jesús Coronel, Sor María de Agreda. Fray Damián Manzanet had specifically been given instructions to look for the tribes that Sor María de Agreda had visited in her religious ecstasy. The Franciscan found the tribes in Texas, and
. . . Manzanet and his companions were joyfully and kindly received and shown every consideration. The Governor, or Chief, of the Tejas Indians one day asked Manzanet for some blue baize in which to bury his grandmother when she died.
Manzanet asked him why he desired it blue. The Chief replied that it was because a beautiful woman who had come often to visit their tribe and whom they reverenced wore blue, and they wished to be like her on passing to the other world … she had promised them teachers, and now that Manzanet and his companions had come, the "high priest" or medicine man of the tribe had told them that these were the true teachers who had been expected.
The strange part of the story is that Mary de Agreda had never really been in Texas or the New World in person, but during her state of intense longing and continued prayer, she must have dreamt or visited them in ecstasy…. She conversed with these dream people and promised them teachers which she finally caused to be sent as we have seen. Numerous were her writings descriptive of these people, their country, customs, and names of tribes, and it was afterwards found to be correct and true. (de Zavala 101-102)"
Back to the Tejas site:
"1806 United States signs Treaty with Tejas Indians - after a Trial governing slavery - happens in the sacred grove of now where Tyler Texas is - the Freeman, Freedman, Freidman Act was made."
Texas wasn't part of the US at the time. The Caddo did sign a treaty with Anglos in 1835, with the Republic of Texas. I couldn't find any site that said the US ever had a treaty with Caddos in that year, outside of the Tejas site.
"(1822) Mexico loses the war with the Tejas Indians and Santa Anna offers surrender terms. El Presidente signs Peace treaty signing over miles of land of Mexico, including deeding claims to Tejas proper to Chief Rosebud for the rape and murder of his quintuple daughters. The lands also ceded is along the width approximately 500 to 700 miles wide and continues down the length of the Rio Grande past Brownsville and by El Paso on the current Mexican side of the border."
Santa Anna wasn't the leader of Mexico in 1822. He was still just a general. Augustin Iturbide ruled Mexico and had the title of emperor, not presidente.
I couldn't find any record of a treaty between Mexico and the Caddo or Tejas in that year. The land that they claim the treaty gave them would have included a number of Mexican towns on the Rio Grande and pretty big land grants already controlled by big landowners. Basically they're claiming the southeastern third of the whole state.
The only Chief Rosebud I could find mentioned online was an Assiniboine chief who met Lewis and Clark, plus one that shows up in a western novel.
"Maribar Lamar becomes President of the Republic of Texas and orders the extinction of the Tejas Indians. He offers blood money in gold silver and paper money to scalp, cripple and maim men, woman and children"
That's Mirabeau Lamar, but otherwise it's accurate except that scalps were offered on most tribes.
"-Tetanka shata - now known as Hops on Left Foot leaves South East Texas,"
Someone correct me, but that name sounds Lakota to me.
"close to Alto after being raped and her right leg cut off and she escapes to Big Sky Tejas place of the sacred rocks (see story of Sister Moon) (now where Boulder, Colorado is) with three hundred orphan and maimed children - starts a village in the rocky mountains. Quatrell meets a mountain man with a pet bear, now named Ben, but was called Brother by the Nation because of the Promise the bear made to the Creator and to Chief Teyas after creation-see oral history. The Mountain Man's name was Addams- Indian stories said that her children be came Sasquache' now also known as Big Foot."
Wait a minute, they're claiming to be Sasquatches?
"Lamar pays $10.00 in gold for each foot of a woman that was cut off, $ 2.50 for each hand of a child and $ 50 in silver and gold, for each scalp taken from a Tejas. Thousands were maimed and died due to their injuries and were murdered - killed out right. Some Tejas take refuge in other Native American Sovereign Nations, and others in old Mexico, and New France (Canada) as well as other Territories."
No doubt many did seek refuge with other tribes. But they would have been adopted in, probably, and no longer thought of themselves as Caddo or Tejas perhaps.
"(1900) 200 Tejas loose their lives in Hurricane Galviston"
I have a hard time believing 200 Caddos could hide out in Galveston and never let anyone notice they were NDN.
"(1901) The Great Little Council of Nacodoches (Hasinai Confederacy) meets and places practice of cannibalism of ones enemies status as no longer active."
Somehow I think that if they'd been eating people in 1900, it would've attracted attention.
"(1920) The practice of general polygamy, multiple wives is set aside reserved for that of the chiefs only."
Same thing with polygamy.
"(1930-39) The State of Texas informally recognized the Tejas Indians- As Its name Sake- makes law required practice to teach about Tejas Indians in Texas History classes."
That's quite a stretch.
"(1950-1959) Indonesia and the Philippines sign friendship treaty with Tejas Indians."
That's the biggest stretch yet. And a treaty doesn't have a date of nine years on it.
"(2005-2006) RADAR/ REACT is activated by the Great Council of Chiefs
local cities and Regains receive aid from the Tejas Indians."
"Hurricanes Katrina, Rita and Wilma causes the deaths of many Tejas. The Tejas loose their main Archives to Vandals In New Orleans. Many archives and artifacts destroyed and or stolen. The disaster causes them to become scattered once again. This, along with the grass fires of the planes in north Texas and of the West affect the Tejas Indian Nation gravely. The Great Little Council of Nacodoches meets, discusses issues on New Orleans and thus issues a reminder to Mayor Ray Neagan of New Orleans that New Orleans sits in Indian Country and on Indian Lands and is not a Chocolate City."
Well, the loss of archives is mighty convenient.
I doubt that Mayor Neagin paid them any attention. Probably thought they were Mardi Gras "Indians."
Found a much better history of the Caddos.
