Background Ethnography is embedded in the history of research and has been considered a methodology in its own right. Its long history means those new to ethnography may find it complex to navigate the differing perspectives and its historical context. Philosophical perspectives further compound the complexities of understanding and making decisions about method. Aim To introduce the historical context of ethnography and its wide-ranging and differing perspectives. Discussion This paper provides an overview of the historical context of ethnography and discusses the different approaches to ethnography based on philosophical paradigms. Examples of ethnographic research in nursing literature are used to illustrate how these different approaches and types of ethnography can be used in nursing. Conclusion Ethnographic research has much to contribute to nursing knowledge. However, it is important to understand the philosophical influences when making decisions about research approach. Implications for practice This article provides an overview of the historic context of ethnography and may improve the knowledge of nurses wishing to employ ethnographic approaches in their own post-graduate and doctoral research.
