There are a couple of ways to view your recent history on eBay:

Viewing recent categories

You can view your three most recent categories on the main page of the Buy section. (You must be logged in.) To clear the items on this list, click the "Clear" link.

Viewing recently viewed items and searches

You can view the last three items you viewed and the last three searches you performed at the bottom of the search results and listings pages. For recently viewed items, you can save the item to your watch list, as well as view the seller's other items and view similar items.

To remove your last three items and searches, click the "Clear all" link.

If you would prefer to hide your recently viewed items and searches, you can disable this feature. Go to My eBay, and click the "Preferences" link in the left column. Scroll down to the General Preferences section, and click the "Show" link next to My eBay. Make your selections, and click the Apply button.

Note: This feature is not implemented on all eBay sites.
