This work includes a sample of 713 spectroscopically classified M0-M8 dwarfs with new rotation rates measured from K2 light curves. We analyze data and recover rotation rates for 179 of these objects. We add these to rotation rates for members of clusters with known ages (5-700Myr), as well as objects assumed to have field ages (>~1Gyr). We use Gaia DR2 parallax and (G-G_RP_) photometry to create color-magnitude diagrams to compare objects across samples. We use color-period plots to analyze the period distributions across age, as well as incorporate H{alpha} equivalent width and tangential velocity where possible to further comment on age dependence. We find that the age of transition from rapid to slow rotation in clusters, which we define as an elbow in the period-color plots, depends on spectral type. Later spectral types transition at older ages: M4 for Praesepe at ~700Myr, one of the oldest clusters for which M dwarf rotation rates have been measured. The transition from active to inactive H{alpha} equivalent width also occurs at this elbow, as objects transition from rapid rotation to the slowly rotating sequence. Redder or smaller stars remain active at older ages. Finally, using Gaia kinematics we find evidence for rotation stalling for late Ms in the field sample, suggesting the transition happens much later for mid- to late-type M dwarfs.2021ApJ...916...77Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/916/77CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/198 : Palomar/MSU nearby star spectroscopic survey (Hawley+ 1997)IV/34 : K2 Ecliptic Plane Input Catalog (EPIC) (Huber+, 2017)I/345 : Gaia DR2 (Gaia Collaboration, 2018)V/154 : Sloan Digital Sky Surveys (SDSS), Release 16 (DR16) (Ahumada+, 2020)J/A+A/327/1039 : Structure and evolution of low-mass stars (Chabrier+ 1997)J/A+A/397/147 : Activity-rotation relationship in stars (Pizzolato+ 2003)J/A+A/430/1005 : VRIH{alpha} photometry of NGC 2264 variables (Lamm+, 2005)J/MNRAS/370/954 : VRIHalpha photometry of M34 (Irwin+, 2006)J/AJ/133/2258 : Activity and kinematics of ultracool dwarfs (Schmidt+, 2007)J/MNRAS/384/675 : Monitoring low-mass stars in NGC 2362 (Irwin+ 2008)J/MNRAS/383/1588 : VIc photometry of NGC 2547 low-mass stars (Irwin+, 2008)J/ApJ/687/1264 : Age estimation for solar-type dwarfs (Mamajek+, 2008)J/AJ/135/785 : SDSS-DR5 low-mass star spectroscopic sample (West+, 2008)J/AJ/137/1 : PMs and astrometry of late-type dwarfs (Faherty+, 2009)J/ApJ/691/342 : griBVI photometry in M37 (Hartman+, 2009)J/MNRAS/392/1456 : VIc phot. of M50 (NGC 2323) low-mass stars (Irwin+, 2009)J/A+A/515/A100 : VI light curves of NGC 1039 solar-type stars (James+, 2010)J/MNRAS/402/620 : SDSS WD main-sequence binaries (Rebassa-Mansergas+, 2010)J/ApJ/733/L9 : Stellar rotation for 71 NGC 6811 members (Meibom+, 2011)J/ApJ/733/115 : Rotation periods and membership in M34 (Meibom+, 2011)J/AJ/141/97 : SDSS DR7 M dwarfs (West+, 2011)J/MNRAS/432/1203 : Rotation periods of M-dwarf stars (McQuillan+, 2013)J/ApJ/795/161 : Activity & rotation in Praesepe & Hyades (Douglas+, 2014)J/ApJS/211/24 : Rotation periods of Kepler MS stars (McQuillan+, 2014)J/MNRAS/454/593 : Young moving groups in solar neighbourhood (Bell+, 2015)J/ApJ/807/45 : Habitable planet search around M dwarfs (Dressing+, 2015)J/ApJ/810/158 : M,L,T dwarfs fundamental param. and SEDs (Filippazzo+, 2015)J/ApJ/804/64 : Empirical and model parameters of 183 M dwarfs (Mann+, 2015)J/AJ/149/158 : The BUD sample.
