This article analyses efforts by subregional government to plan for and implement language policy (LP). It aims to show that this governance level is key to a more nuanced understanding of the locations within which language policies are created, brought to fruition and evaluated. With this in mind, data from six subregional authorities in the Autonomous Community of the Basque Country, the Autonomous Community of Catalonia and Wales are employed. Additionally, from the particularity of each region and subregional authority, these data are applied more generally to analyse party political support for LP activity as well as LP interaction across governance tiers. This paper discusses the extent to which regional governments’ legislative and fiscal support (or relative lack of support) for overall LP objectives influences, restricts or otherwise engages subregional government LP activity. Understanding the relationship between the first two objectives will help to link local empirical data with the third objective—that of beginning to unravel the role that non-statewide nationalist and regional branches of statewide political parties play as LP facilitators at both subregional and regional level. Party activity in LP is subsequently interpreted as a measure through which to emphasize the values of (often overlapping) identity and solidarity patterns.
