Who was not a key player in the Santa Fe Ring?

The Santa Fe Ring was a powerful political and economic faction in New Mexico during the late 19th century. It included a variety of influential figures, primarily politicians and land speculators, who were involved in corrupt practices to control land and resources in the region.

Lucian Maxwell, while being an important figure in New Mexico's land history, was not a core member of the Santa Fe Ring. His involvement was more about his own land holdings and business interests rather than the organized corruption and manipulation that characterized the Ring.

In contrast, a secret group of Republicans was indeed associated with the Santa Fe Ring, as many members of this faction were politically connected Republicans. Similarly, the description of a group of influential people who controlled economics through murder and threats is an accurate characterization of the darker aspects of the Ring's operations. Catron and Elkins were also prominent figures within the Santa Fe Ring who played significant roles in its activities and influence within the territory.

Thus, the choice identifying Lucian Maxwell as not being a key player aligns with the understanding of the Santa Fe Ring's primary members and their tactics.
