MEMORANDUM **

California state prisoner Abdelkaker Morceli appeals pro se from the district court’s summary judgment.in his 42 U.S.C. § 1983 action alleging a violation of his First Amendment free exercise rights. We have jurisdiction under 28 U.S.C. § 1291. We review de novo, Jones v. Williams, 791 F.3d 1023, 1030 (9th Cir. 2015), and we affirm.

The district court properly granted summary judgment because Morceli failed to raise a genuine dispute of material fact as to whether defendant was responsible for the challenged headwear policy’s creation and enforcement. See id. at 1031-32 (setting forth elements of a § 1983 free exercise claim); Starr v. Baca, 652 F.3d 1202, 1207-08 (9th Cir. 2011) (setting forth elements for supervisory liability under § 1983). Contrary to Morceli’s contentions, the district court applied the proper standard under Federal Rule of Civil Procedure 56 in granting summary judgment where Morceli’s contentions were not supported by facts. See Arpin v. Santa Clara Valley Transp. Agency, 261 F.3d 912, 922 (9th Cir. 2001) (“[Cjonclusory allegations unsupported by factual data are insufficient to defeat [a defendant’s] summary judgment motion.”).

AFFIRMED.
