There are a number of independent national fellowships in the humanities that provide support for research and writing. The list below is necessarily non-exhaustive, but the following organizations offer external dissertation fellowships for which classicists and specialists in late antique, patristic, early Christian, and medieval topics may be qualified. Some of these may be held in any location; others are confined to the US or to locations overseas.

• The American Association of University Women Dissertation Fellowships
• The American School of Classical Studies at Athens (various fellowships)
• The Dumbarton Oaks Junior Fellowships
• The Fulbright Scholarships
• The Josephine De Kármán Fellowships
• The Mellon/ACLS Dissertation Completion Fellowships
• The Mellon Fellowships for Dissertation Research in Original Sources
• The Charlotte W. Newcombe Doctoral Dissertation Fellowships
• The Rome Prize Pre-Doctoral Fellowships
• The Mary Isabel Sibley Fellowship of Phi Beta Kappa

For additional leads, the following websites are also recommended (some repeated from above for convenience):

• Harvard University's graduate grant database (recommended by the School of Theology and Religious Studies)
• Princeton University's list of external graduate fellowships
• The German Studies Network list of resources for dissertation research in German-speaking countries (Germany, Austria, and Switzerland)

Do not forget to check with the graduate academic and deans' offices at your university for additional information on potential sources of dissertation support. Even if no internal university fellowships are available, many external organizations solicit applications by sending informational materials to deans, rather than to departments.
