The Spanish had the friendliest relationship with Hasinai Indians in the late 1600's.
Explanation:
In the earlier years, the Jumano Indians were in a quest to establish friendly relations with the Spanish but the Spanish didn't look at their relation with the Jumanos as strategically important.
In the late 1600's, the Spanish realised that establishing friendly relations with the Hasinai Indians would help them in a number of ways. The Spanish had already devised that they needed the support of the Hasinais to prosper in the region.
