Launched by Oxford Constitutional Law, this Timeline of the United States' Constitutional Law provides an overview of legal history from the Magna Carta to the present day. The interactive timeline invites users to scroll through centuries of history, delving into landmark cases and major moments from the past. Some of these events will likely refresh your prior knowledge, but other events are less well-known (e.g. the dates of each state's constitutional ratification). The included case law highlights monumental legal decisions (such as Brown v. Board of Education, which declared school segregation unconstitutional, and Obergefell v. Hodges, which "ruled that the fundamental right to marry is guaranteed to same-sex couples by both the Due Process Clause and the Equal Protection Clause of the Fourteenth Amendment to the United States Constitution,"). In addition to the picture and caption provided for each event, many slides embed links to other Oxford Reference documents that provide further information. Readers should note that access to some of the embedded Oxford articles and tools requires a subscription. However, many of the documents have abstracts available to non-subscribers.
