The timeline below depicts influential events in the world, the United States, or in the territory or state of Iowa. The timeline holds events that pertain to all major themes presented within the Iowa Pathways website.

Navigating the Timeline

Each notable event recorded on the timeline has its own slide. Use the large arrow on the right to move to the next event in time. Use the large arrow on the left to move back to the previous event in time. Select an event in the timeline to move to that event.

Below the slide deck, on the left side are two magnifying glasses. Use the plus sign magnifying glass to zoom in on the timeline. Use the minus sign magnifying glass to zoom out on the timeline. As you zoom in and out, you will see the timeline under the slide deck expand and retract based on magnification. The back arrow below the magnifying glasses will restart the timeline.

What’s on each slide:

  • Each slide is color-coded. Dark red are world events; yellow are United States events; and dark blue are Iowa events.
  • Where appropriate, media that supports or explains the event has been added to enrich your experience. Select the media within the slide to view the information.
  • Where appropriate, you can find additional Iowa Pathways information about the event by selecting the link provided within the slide.
