I ended up using www.dipity.com for building this one. Others you might want to take a look at (my diigo on this topic): This list is from Richard Byrne website.
- Meograph offers a nice way to create narrated map-based and timeline-based stories.
- Dipity is a great timeline creation tool that allows users to incorporate text, images, and videos into each entry on their timeline.
- myHistro is a timeline builder and map creation tool rolled into one nice package. On myHistro you can build a personal timeline or build a timeline about a theme or event in history. Each event that you place on your timeline can be geolocated using Google Maps. myHistrotimelines can be created online or you can use the free iPad app to create events on your timeline.
- I like XTimeline because I find it to be a great service that is very accessible to high school students. Using XTimeline students can collaborate, just as they would when making a wiki, to build a multimedia timeline.
- TimeGlider offers some nicer layout features compared to XTimeline, but is not quite as intuitive to use as XTimeline.
- Time Toast is easy to learn to use. To add events to a timeline simply click on the inconspicuous "add an event" button and a simple event box pops up in which you can enter enter text, place a link, or add a picture.
So in 30-40 minutes I built the following timeline to help students understand what might have been lost if Greece had fallen to the Persians. You will have to zoom in see the timeline on Ancient Greece. Be sure to click the "flipbook" and "list" view.
