In 1993, then-U.S. President Bill Clinton oversaw the construction of the first stretch of the U.S.-Mexico border walls. Since that pivotal moment, every subsequent U.S. president has allowed for the construction of additional miles of walls or fences. Despite his initial pledge to halt the expansion of border walls, in July 2022, President Joe Biden authorized the construction of new sections in four locations within Arizona. This decision underscores the enduring complexity and contentious nature of the U.S.-Mexico border infrastructure.
 
From the bustling San Diego–Tijuana region to the borderlands of Brownsville-Matamoros, the U.S.-Mexico border is marked by extensive stretches of walls. Over the past thirty years, these walls have evolved from purely physical barriers into multifaceted systems encompassing administrative, legal, legislative, and biometric components. This volume invites readers to reflect on the transformations of the border since the construction of the initial fourteen miles of wall, and the subsequent addition of 1,940 miles. It provides a comprehensive exploration of the border’s evolution, and its profound and lasting impacts.
 
Bringing together recognized scholars in border studies, Walled delves into the varied manifestations and lived experiences associated with U.S.-Mexico border walls. The introduction by Andréanne Bissonnette and Élisabeth Vallet offers a thorough review of the border walls’ thirty-year history, placing it within a global context. Contributions offer diverse perspectives of the border experience, from state policies and migrant experiences to the daily lives of border residents. Topics such as militarization, migration, artistic resistance, and humanitarian aid are carefully examined. This volume is an essential resource for policymakers, activists, scholars, and anyone seeking to understand the intricate realities of border communities and the far-reaching consequences of border policies.

Even as Donald Trump’s election has galvanized anti-immigration politics, many local governments have welcomed immigrants, some even going so far as to declare their communities “sanctuary cities” that will limit cooperation with federal immigration authorities. But efforts to assist immigrants are not limited to large, politically liberal cities. Since the 1990s, many small to mid-sized cities and towns across the United States have implemented a range of informal practices that help immigrant populations integrate into their communities.

Abigail Fisher Williamson explores why and how local governments across the country are taking steps to accommodate immigrants, sometimes despite serious political opposition. Drawing on case studies of four new immigrant destinations—Lewiston, Maine; Wausau, Wisconsin; Elgin, Illinois; and Yakima, Washington—as well as a national survey of local government officials, she finds that local capacity and immigrant visibility influence whether local governments take action to respond to immigrants. State and federal policies and national political rhetoric shape officials’ framing of immigrants, thereby influencing how municipalities respond. Despite the devolution of federal immigration enforcement and the increasingly polarized national debate, local officials face on balance distinct legal and economic incentives to welcome immigrants that the public does not necessarily share. Officials’ efforts to promote incorporation can therefore result in backlash unless they carefully attend to both aiding immigrants and increasing public acceptance. Bringing her findings into the present, Williamson takes up the question of whether the current trend toward accommodation will continue given Trump’s anti-immigrant rhetoric and changes in federal immigration policy.
