In his introduction, Professor Stuart Banner explains the origin of his book and sets out a very useful model for how he will be telling this history.
First, he realized his own uncertainty, as a college history professor to answer students questions about the issue stated in the title. Second, he suggests that a key question is how, over time, we can characterize Indian land sales as being voluntary, involuntary, or somewhere in between.
The book is divided chronologically based on changes in this process. First, early English colonizers did recognize Natives as owning their land, even where there was actual sovereignty as political units. In this time, Banner also showed how individual colonists and colonial goverments sought to buy Indian land, even as their presence and encroachment began undermining Native economic systems that assumed ownership and control over open hunting land as much as farming land.
Second, by the late colonial era and early 1800s, English colonists and new Americans were no longer in constant contact with Native people on a regular basis. Instead, they often relied on European theorists and concluded Natives were only hunters, which undermined their prior sense that Indians owned the land on which the were located. In turn, the American national government began to forbid private purchases from Native nations, in favor of only the Federal government being the sole possible buyer.
Next, the formal removal error of the Jacksonian presidency is seen by Banner as a larger scale, quicker version of the long history of individuals and governments buying Native land. Here, though, he argues, we see a much less free option for Natives. Reservations emerge thusly as another possible way to resolve the American desire to take over Native land and yet allow Native nations to remain, somewhere.
In this regard, Banner argues that white settlers refused to actually respect Native reservation's boundaries. Still, we find that settlers continued seeking to take and encroach on Indian land. Their view was that white Americans should be able to take the land and use it more intensively rather than having a continuing small number of Native people to be on this land.
The next Federal policy discussed was allotment. In the later 1800s, the Federal government sought to divide trial lands and give Native heads of household permanent title to land, to replace a Native understanding of individual ownership as being about current use rights. (He says this happened all over the world to indigenous peoples in areas colonized by English-speaking people such as in Australia). This was intended to create more incentive to productivity for Native people individually and get more Indian lands into the hands of white American colonists.
The story Banner tells ends, in any detail, in 1934. Here, the Federal government abandons allotment Even today, Native land remains possessed by Indian tribes, not be individual Native people. In a brief epilogue, Dr. Banner suggest that, in the past few decades, Native nations' rights have been much more respected in American law. He could have added, I think, a bit more about how changes in American culture has allowed for this trend. Yet, what was intriguing was his assertion that American courts are agreeing, in some cases, that many of the treaties and land sale contracts that transferred Native lands to American hands were actually legally invalid when they took place.
Very fascinating book and well worth the time spent to read it.
