Will you be conducting any business whatsoever while you are in Europe, such as attending a seminar or conference or taking a class? Or is this strictly a personal trip that has interest to you because of your teaching experience in European HIstory?
The tax law expressly prohibits deducting expenses for travel as a form of education or for reasons of pleasure only. Travel expenses for overseas travel are also more limited than expenses allowed for travel in the United States, but a portion of your trip has to include a business purpose. Your trip does not have to be entirely business to deduct a portion of the expenses, but you would have to have some legitimate business purpose included as part of your trip. If less than 75% of your foreign travel is related to business, your deductions are subject to limitations and allocation.
It does not sound like you would qualify to take any deductions if your trip is mainly for pleasure. If you were attending a class which helped improve your current skills, or attending a seminar or convention or something of that nature, then you would possibly be allowed to deduct a portion of your expenses.
